Shen Feng 7e5a8cdd84 ext4: fix error processing in mb_free_blocks
The error processing of the return value of mb_free_blocks is meanless
because it only returns 0.  This fix includes

- make mb_free_blocks return void

- remove the error processing part in callers

- unlock group before calling ext4_error in mb_free_blocks
