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
85975426 22294712 20627456 128897594 7aed23a vmlinux.before
85842882 22294584 20627456 128764922 7accbfa vmlinux

[mkp: Removed unused __bfa_trc32()]
