ewah: delete unused 'rlwit_discharge_empty()'

Complete the removal of unused 'ewah bitmap' code by removing the now unused 'rlwit_discharge_empty()' function. Also, the 'ewah_clear()' function can now be made a file-scope static symbol. Signed-off-by: Ramsay Jones <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>
