amdgcn, libgomp: Remove unused variable (PR121156)

There's a new compiler warning breaking the build.  This fixes it.  The
variable appears to be genuinely vestigial.

libgomp/ChangeLog:

	PR target/121156
	* config/gcn/bar.c (gomp_team_barrier_wait_end): Remove unused
	"generation" variable.
	(gomp_team_barrier_wait_cancel_end): Likewise.
