r8152: fix the firmware doesn't work
generic_ocp_write() asks the parameter "size" must be 4 bytes align.
Therefore, write the bp would fail, if the mac->bp_num is odd. Align the
size to 4 for fixing it. The way may write an extra bp, but the
rtl8152_is_fw_mac_ok() makes sure the value must be 0 for the bp whose
index is more than mac->bp_num. That is, there is no influence for the
firmware.
Besides, I check the return value of generic_ocp_write() to make sure
everything is correct.
