btrfs: can_nocow_file_extent should pass down args->strict from callers

Commit 619104ba453ad0 ("btrfs: move common NOCOW checks against a file
extent into a helper") changed our call to btrfs_cross_ref_exist() to
always pass false for the 'strict' parameter.  We're passing this down
through the stack so that we can do a full check for cross references
during swapfile activation.

With strict always false, this test fails:

  btrfs subvol create swappy
  chattr +C swappy
  fallocate -l1G swappy/swapfile
  chmod 600 swappy/swapfile
  mkswap swappy/swapfile

  btrfs subvol snap swappy swapsnap
  btrfs subvol del -C swapsnap

  btrfs fi sync /
  sync;sync;sync

  swapon swappy/swapfile

The fix is to just use args->strict, and everyone except swapfile
activation is passing false.
