Subject: [PATCH 3/4] staging: r8188eu: convert ODM_ReadAndConfig_PHY_REG_1T_8188E() to int

The function ODM_ReadAndConfig_PHY_REG_1T_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.
