target/m68k: fix gen_get_ccr()

Browse source 
As gen_helper_get_ccr() is able to compute CCR from cc_op and
flags, we don't need to flush flags before to call it.
flush_flags() and get_ccr() use COMPUTE_CCR() to compute
flags. get_ccr() computes CCR value,
whereas flush_flags update live cc_op and flags.
