checkpatch: Avoid some false positives for TABSTOP declaration test

From: Joe Perches
Date: Thu Jan 11 2018 - 16:01:26 EST


Using an open bracket after what seems to be a declaration
can also be a function definition and declaration argument
line continuation so remove the open bracket from the
possible declaration/definition matching.

e.g.:
int foobar(int a;
int *b[]);
