Milan Broz ce23225e46 Check if provided cipher and mode is usable before writing LUKS header to disk. ...

If user provided unusable cipher-mode string, LUKS header was written and
keyslot creation failed later.

Better check early (by creating fake dmcrypt device) if cipher is usable
and fail early (without writing LUKS header to device).

Fixes Issue#176
