brcm80211: smac: avoid sprom endianess conversions for crc8 check
The data from the sprom consists of u16 values stored in little endian notation over which a crc8 was determined. To validate this the buffer needed to be converted for big-endian systems. Reading the sprom data is now done per byte so conversion is only done after a successful crc8 check.
