btrfs: fix warning on PTR_ERR() against NULL device at btrfs_control_ioctl()
Smatch complains about calling PTR_ERR() against a NULL pointer:
fs/btrfs/super.c:2272 btrfs_control_ioctl() warn: passing zero to 'PTR_ERR'
Fix this by calling PTR_ERR() against the device pointer only if it
contains an error.
