c-parser.c replace error() by error_at()

[Prathamesh Kulkarni]

Replace calls to error() by error_at().

* c-parser.c (c_parser_declspecs): replace call to error () by error_at ()
* c-parser.c (c_parser_parameter_declaration): Likewise

Bootstrapped on x86_64-unknown-linux-gnu
Ok for trunk ?

Thanks and Regards,
Prathamesh
