crypto: api - Call crypto_alg_put in crypto_unregister_alg

BugLink: https://bugs.launchpad.net/bugs/2107212

[ Upstream commit 27b13425349e94ad77b174b032674097cab241c8 ]

Instead of calling cra_destroy by hand, call it through
crypto_alg_put so that the correct unwinding functions are called
through crypto_destroy_alg.
