[PATCH] Fix a pasto in gfc_check_num_images

[Jakub Jelinek]

Hi!

bootstrap-ubsan reported taking address of a &distance->where when
distance is NULL.  The function has one block guarded with if (distance)
and another guarded with if (failed), so I think this is just a pasto
from the earlier if (distance) block.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
