brcmsmac: fix uninitialized variable warning on arm architecture 



Using gcc v4.7.2 gave following warning:

  CC [M]  drivers/net/wireless/brcm80211/brcmsmac/aiutils.o
brcmsmac/aiutils.c: In function 'ai_deviceremoved':
brcmsmac/aiutils.c:733:9: error: 'w' may be used uninitialized
in this function [-Werror=uninitialized]

Inspection of the pci_read_config_dword() function showed it can
return without modifying the output variable 'w' so this patch
initializes it to 0.
