Subject: [PATCH v2] staging: rtl8723bs: os_dep: simplify the return statement.

Remove the unneeded and redundant check of variable on goto out.
Simplify the return using multiple goto label to avoid
unneeded check.

ChangeLog V2:
	-Add goto out after the memcpy for no error case return with
	 ret only. Free is not required on no error case.

ChangeLog V1:
	-Remove the unneeded and redundant check of variable on
	 goto out.
	-Simplify the return using multiple goto label to avoid
	 unneeded check.
