lldap: fix the building failure when gcc5 is used or DEBUG_BUILD is 1

1. fix the building failure when host is gcc5
2. fix the building failure when DEBUG_BUILD is 1 by removal of -Werror
   Remove -Werror, since it is suitable to develop only; otherwise when
   gcc adds -O0 option to compile codes, the error will be generated
   since the warning:
     //#  warning _FORTIFY_SOURCE requires compiling with optimization (-O)

+Subject: [PATCH] get inline functions work with both gnu11 and gnu89
+
+Upstream-status: Pending
+
+After gcc upgraded to gcc5, and if the codes are compiled without optimization(-O0),
+and the below error will happen:
+
+./include/lldp_8021qaz.h:237:12: error: inline function 'ieee8021qaz_clif_cmd' declared but never defined [-Werror]
+ inline int ieee8021qaz_clif_cmd(void *data, struct sockaddr_un *from,
+            ^
+./include/lldp_8021qaz.h:222:13: error: inline function 'set_prio_map' declared but never defined [-Werror]
+ inline void set_prio_map(u32 *prio_map, u8 prio, int tc);
+             ^
+./include/lldp_8021qaz.h:221:12: error: inline function 'get_prio_map' declared but never defined [-Werror]
+ inline int get_prio_map(u32 prio_map, int tc);
+
+gcc5 defaults to -std=gnu11 instead of -std=gnu89, and it requires that exactly one C
+source file has the callable copy of the inline function. Consider the following
+program:
+
+  inline int
+  foo (void)
+  {
+    return 42;
+  }
+
+  int
+  main (void)
+  {
+    return foo ();
+  }
+
+The program above will not link with the C99 inline semantics, because no out-of-line
+function foo is generated. To fix this, either mark the function foo as static, or
+add the following declaration:
+  static inline int foo (void);
+
+more information refer to: https://gcc.gnu.org/gcc-5/porting_to.html;
+
+but the use of "extern inline" will lead to the compilation issue if gcc is not
+gcc5, so replace inline with "static inline"
