target/arm_adi_v5: Fix clear sticky overrun flag during replay of commands 

When a WAIT occurs the commands after the WAIT are replayed and the
STICKYORUN is cleared. However if another WAIT occurs during the
command replay, the command itself is resent but the STICKYORUN bit
shall also be cleared. If this is not done, the MEM-AP hangs.
