btrfs: Rename __btrfs_alloc_chunk to btrfs_alloc_chunk
Having btrfs_alloc_chunk doesn't bring any value since it
encapsulates a lockdep assert and a call to find_next_chunk. Simply
rename the internal __btrfs_alloc_chunk function to the public one
and remove it's 2nd parameter as all callers always pass the return
value of find_next_chunk. Finally, migrate the call to
lockdep_assert_held so as to not lose the check.
