[PR118560][LRA]: Fix typo in checking secondary memory mode for the reg class

  The patch for PR118067 wrongly checked hard reg set subset.  It worked for
the equal sets as in PR118067.  But it was wrong in other cases as in
PR118560 (inordinate compile time).

gcc/ChangeLog:

	PR target/118560
	* lra-constraints.cc (invalid_mode_reg_p): Exchange args in
	hard_reg_set_subset_p call.
