Subject: [PATCH 3/5] staging: r8188eu: convert rtw_init_cmd_priv() to common error logic

Convert the function rtw_init_cmd_priv() to common kernel error logic.
Return 0 on success and negative value on failure. This is part of
getting rid of returning _SUCCESS and _FAIL which uses inverted error
logic and is used all over the driver.
