crash_dump: retrieve dm crypt keys in kdump kernel
Crash kernel will retrieve the dm crypt keys based on the dmcryptkeys
command line parameter. When user space writes the key description to
/sys/kernel/config/crash_dm_crypt_key/restore, the crash kernel will save
the encryption keys to the user keyring. Then user space e.g.
cryptsetup's --volume-key-keyring API can use it to unlock the encrypted
device.
