btrfs: restore the thread_pool= behavior in remount for the end I/O workqueues 



Commit d7b9416f ("btrfs: remove btrfs_end_io_wq") converted the read
and I/O handling from btrfs_workqueues to Linux workqueues, and as part
of that lost the code to apply the thread_pool= based max_active limit
on remount.  Restore it.
