bfa: deinline __bfa_trc() and __bfa_trc32()
__bfa_trc() compiles to 115 bytes of machine code.
With this .config: http://busybox.net/~vda/kernel_config
there are 1494 calls of __bfa_trc().
__bfa_trc32() is very similar, so it is uninlined too.
However, it appears to be unused, therefore this patch
ifdefs it out.
Change in code size is about 130,000 bytes:
text data bss dec hex filename

[mkp: Removed unused __bfa_trc32()]
