Tetsuo Handa 08dee81491 PM / hibernate: Fix oops at snapshot_write()
commit fc14eebfc2 upstream.

syzbot is reporting NULL pointer dereference at snapshot_write() [1].
This is because data->handle is zero-cleared by ioctl(SNAPSHOT_FREE).
Fix this by checking data_of(data->handle) != NULL before using it.
