Switch away from accessing volume key internals directly.

Browse Source 
Switch current code to use following volume key helpers
for accessing internal properties:

crypt_volume_key_length(), crypt_volume_key_get_key(),
crypt_volume_key_description() and crypt_volume_key_kernel_key_type()

Remaining direct access to volume key internals will be dealt with in
later commits since it requires some further changes.
