[PATCH 1/6] brcmfmac: switch to C function (__brcmf_err) for printing errors

["Rafał Miłecki" <zajec5@gmail.com>]

From: Rafał Miłecki <rafal@milecki.pl>

This will allow extending code and using more detailed messages e.g.
with the help of dev_err. Note that *two separated* brcmf_err macros
were replaced thanks to using a simple CONFIG_BRCMDBG symbol check in
the body.
