[2/4] staging: r8188eu: convert rtw_xmit_resource_alloc() to common error logic
Commit Message
Convert the function rtw_xmit_resource_alloc() away from returning
_FAIL or _SUCCESS which uses inverted error logic. Use the common
error logic instead. Return 0 for success and negative values for
failure.
