Btrfs: rework error handling in btrfs_mount() Commits 6c41761f and 45ea6095 introduced the possibility of NULL pointer dereference on error paths, also we would leave all devices busy and leak fs_info with all sub-structures on error when trying to mount an already mounted fs to a different directory. Fix this by doing all allocations before trying to open any of the devices, adjust error path for mount-already-mounted-fs case. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
