Fortran: fix passing of component ref to assumed-rank dummy [PR118683]

While the fix for pr117774 addressed the passing of an inquiry reference
to an assumed-rank dummy, it missed the similar case of passing a component
reference.  The newer testcase gfortran.dg/pr81978.f90 uncovered this
latent issue with a UBSAN instrumented compiler.

	PR fortran/118683

gcc/fortran/ChangeLog:

	* trans-expr.cc (gfc_conv_procedure_call): The bounds update for
	passing to assumed-rank dummies shall also handle component
	references besides inquiry references.
