The purpose of this function is to unlock all nodes in a btrfs path
which are above 'lowest_unlock' and whose slot used is different than 0.
As such it used slightly awkward structure of 'if' as well as somewhat
cryptic "no_skip" control variable which denotes whether we should
check the current level of skipability or no.
This patch does the following (cosmetic) refactorings:
* Renames 'no_skip' to 'check_skip' and makes it a boolean. This
variable controls whether we are below the lowest_unlock/skip_level
levels.
* Consolidates the 2 conditions which warrant checking whether the
current level should be skipped under 1 common if (check_skip) branch,
this increase indentation level but is not critical.
* Consolidates the 'skip_level < i && i >= lowest_unlock' and
'i >= lowest_unlock && i > skip_level' condition into a common branch
since those are identical.
* Eliminates the local extent_buffer variable as in this case it doesn't
bring anything to function readability.
