[PATCH] checkpatch: Fix $Float creation of match variables

[Joe Perches]

commit 74349bccedb
("checkpatch: add support for floating point constants")
added an unnecessary match variable that caused
tests that used a $Constant or $LvalOrFunc to have
one too many matches.

This causes problems with usleep_range, min/max and
other extended tests.

Avoid using match variables in $Float.
Avoid using match variables in $Assignment too.
