middle-end: Fix mask length arg in call to vect_get_loop_mask [PR96342]

When issuing multiple calls to a simdclone in a vectorized loop,
TYPE_VECTOR_SUBPARTS(vectype) gives the incorrect number when compared
to the TYPE_VECTOR_SUBPARTS result we get from the mask type derived
from the relevant `rgroup_controls' entry within `vect_get_loop_mask'.

By passing `masktype' instead, we are able to get the correct number of
vector subparts and thu eliminate the ICE in the call to
`vect_get_loop_mask' when the data type for which we retrieve the mask
is wider than the one used when defining the mask at mask registration
time.

gcc/ChangeLog:

	PR target/96342
	* tree-vect-stmts.cc (vectorizable_simd_clone_call):
	s/vectype/masktype/ in call to vect_get_loop_mask.
