Subject: [PATCH] qcacmn: Fix NBUF_MEMORY_DEBUG PERF build error

qdf_net_buf_debug_init/exit() are defined when NBUF_MEMORY_DEBUG is
disabled, but they are not declared in the nbuf header file, leading
to build errors for PERF builds. Make qdf_net_buf_debug_init/exit()
static inline stubs when NBUF_MEMORY_DEBUG is disabled.
