crypto: api - Add support for duplicating algorithms before registration
If the bit CRYPTO_ALG_DUP_FIRST is set, an algorithm will be
duplicated by kmemdup before registration. This is inteded for
hardware-based algorithms that may be unplugged at will.
Do not use this if the algorithm data structure is embedded in a
bigger data structure. Perform the duplication in the driver
instead.
