ecryptfs: fix kernel panic with null dev_name
commit 9046625511ad8dfbc8c6c2de16b3532c43d68d48 upstream.
When mounting eCryptfs, a null "dev_name" argument to ecryptfs_mount()
causes a kernel panic if the parsed options are valid. The easiest way to
reproduce this is to call mount() from userspace with an existing
eCryptfs mount's options and a "source" argument of 0.
Error out if "dev_name" is null in ecryptfs_mount()
Fixes: 237fead61998 ("[PATCH] ecryptfs: fs/Makefile and fs/Kconfig")
