Add CRYPT_ACTIVATE_REFRESH flag to activation calls.

Browse Source 
The new flag is supposed to refresh (reload) active dm-crypt
mapping with new set of activation flags. CRYPT_ACTIVATE_READONLY
can not be switched for already active device.

The flag is silently ignored for tcrypt, verity and integrity
devices. LUKS2 with authenticated encryption support is added in
later commit.
