scmutil: skip checks in "casecollisionauditor" if filename is already checked

Before this patch, almost all of check code in
"casecollisionauditor.__call__()" is executed, even if specified
filename is already checked, because "f in self._newfiles" is examined
lastly.

In addition to it, adding "fl" to "self._loweredfiles" and "f" to
"self._newfiles" are also redundant in such case.

This patch checks "f in self._newfiles" first, and returns immediately
to avoid execution of check code for efficiency.
