staging: r8188eu: use a local buffer for efuse data
The efuse_eeprom_data array in struct eeprom_priv is used only by
ReadAdapterInfo8188EU. We can remove efuse_eeprom_data and use a local
buffer instead.
Use EFUSE_MAP_LEN_88E as buffer size. Its value is the same as
HWSET_MAX_SIZE_512. The functions that access the buffer use
EFUSE_MAP_LEN_88E for its size.
