[PATCH 1/4] staging: r8188eu: convert ODM_ReadAndConfig_MAC_REG_8188E() to int

[Michael Straube <straube.linux@gmail.com>]

The function ODM_ReadAndConfig_MAC_REG_8188E() has return type
'enum HAL_STATUS'. Convert the return type to int and use common
kernel error logic. Return 0 on success and negative values on
failure. The goal is to get rid of enum HAL_STATUS in the end.
