Subject: [PATCH -next] brcmfmac: remove set but not used variable 'mpnum','nsp','nmp'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/chip.c: In function brcmf_chip_dmp_get_regaddr:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/chip.c:790:5: warning: variable mpnum set but not used [-Wunused-but-set-variable]

They are introduced by commit 05491d2ccf20 ("brcm80211:
move under broadcom vendor directory"), but never used,
so remove them.

No they are not, that commit only moved the driver into a different
directory. I'll remove that sentence when I commit this.
