[LRA]: Fix asserts for output stack pointer reloads

The patch implementing output stack pointer reloads contained superfluous
asserts.  The patch makes them useful.

gcc/ChangeLog:

	* lra-constraints.cc (curr_insn_transform): Set done_p up and
	check it on true after processing output stack pointer reload.
