[PATCH] mwifiex: Make mwifiex_dbg a function, reduce object size

[Joe Perches <joe@perches.com>]

The mwifiex_dbg macro has two tests that could be consolidated
into a function reducing overall object size ~10KB (~4%).

So convert the macro into a function.

$ size drivers/net/wireless/mwifiex/built-in.o* (x86-64 defconfig)
