btrfs: fix a deadlock in btrfs_scan_one_device() pathname resolution under a global mutex, taken on some paths in ->mount() is a Bad Idea(tm) - think what happens if said pathname resolution triggers automount of some btrfs instance and walks into attempt to grab the same mutex. Deadlock - we are waiting for daemon to finish walking the path, daemon is waiting for us to release the mutex... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
