Revert "btrfs: avoid monopolizing a core when activating a swap file"

This reverts commit 6e1a8225.

The backport for linux-6.6.y, commit 6e1a8225 ("btrfs: avoid
monopolizing a core when activating a swap file"), inserted
cond_resched() in the wrong location.

Revert it now; a subsequent commit will re-backport the original patch.
