Subject: [PATCH] btrfs: block-group: Rework documentation of
 check_system_chunk function

Commit 4617ea3a52cf (" Btrfs: fix necessary chunk tree space calculation
when allocating a chunk") removed the is_allocation argument from
check_system_chunk, since the formula for reserving the necessary space
for allocation or removing a chunk would be the same.

So, rework the comment by removing the mention of is_allocation
argument.
