brcmfmac: fix uninitialized warning
Building brcmfmac for sparc64 gave the following warning:
CC [M] drivers/net/wireless/brcm80211/brcmfmac/bcmsdh_sdmmc.o
bcmsdh_sdmmc.c: In function 'brcmf_sdioh_request_byte':
bcmsdh_sdmmc.c:89:6: warning: 'err_ret' may be used uninitialized
in this function [-Wuninitialized]
Inspecting the code it indeed had a path of execution in
which the return value was used uninitialized. This patch
fixes that code path.
