[gfortran, committed] Fix PR17676 : segfault with user defined operators

[Tobias Schlüter]

This obvious patch fixes a segfault which surprisingly only appeared on sparc.
On i686-pc-linux we take the exact same code path (everything else would be an
error), and don't segfault, even though e->uop->ns is NULL. Maybe some
compiler builtin or macro magic masked the error. I had forgotten about this
patch which had been lying around for two weeks.

Built and tested, committed under the obviously correct rule.
