checkpatch: fix USLEEP_RANGE test
Do not test udelay() for a value less than 10usec when passed a variable
instead of a hard-coded number; there is no way for checkpatch to know the
value of the variable. As it is today, it will complain about variables
with alphanumeric characters plus '_', e.g. foo_bar, but not variables
with other characters, eg. foo->bar.
