[committed] Better location for atomic bit-fields

[Marek Polacek]

A trivial patch to use LOC for atomic bit-fields error messages.
I haven't bothered with a testcase this time.

Bootstrapped/regtested on x86_64-linux, applying to trunk.

        * c-decl.c (grokdeclarator): Call error_at instead of error and pass
        LOC to it.
