[PATCH 4/4] staging: r8188eu: convert PHY_BBConfig8188E() to common error logic

[Michael Straube]

Convert the function PHY_BBConfig8188E() 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.
