David Sterba 99be1a66e1 btrfs: add specific helper for range bit test exists
The existing helper test_range_bit works in two ways, checks if the whole
range contains all the bits, or stop on the first occurrence.  By adding
a specific helper for the latter case, the inner loop can be simplified
and contains fewer conditionals, making it a bit faster.

There's no caller that uses the cached state pointer so this reduces the
argument count further.
