hppa: Fix integer REG+D address reloads

I made a mistake in the previous change to integer_store_memory_operand.
There is no support pa_emit_move sequence to handle secondary reloads of
integer REG+D instructions.  Further, the Q constraint is used for some
non-simple instructions (movb and addib).  Thus, we need to return true
when reload is in progress.

	PR target/112617
	* config/pa/predicates.md (integer_store_memory_operand): Return
	true for REG+D addresses when reload_in_progress is true.
