coccinelle: double_lock: improve performance when no double lock exists

The 'balanced' rule collects the locks that are taken and released
under the same condition, to prevent them from being reported as a
double lock. It runs on every file that contains a lock call.

To avoid this, collect the double-lock candidates first, so that
'balanced' runs only when one exists. The report then excludes what
'balanced' found.

Every double lock that can be reported is also a candidate, so the
same reports are made as before and the output does not change. A
report-mode run over every .c file in the tree produces identical
output.
