[PATCH] [PATCH] staging: rtl8723bs: change error handling to use standard errno

[Omer El Idrissi <omer.e.idrissi@gmail.com>]

Replace non-standard return values with descriptive
linux kernel error codes in probe path.
Also replace the variable name 'status' with 'ret'
to be more consistent with other kernel code
