rS363262: Add crypto_initreq() and crypto_destroyreq().

Summary

These routines are similar to crypto_getreq() and crypto_freereq()
but operate on caller-supplied storage instead of allocating crypto
requests from a UMA zone.

Test Plan

used this with some KTLS performance testing

LGTM aside from the comments.

sys/opencrypto/crypto.c
1768	Style doesn't require the extra newline anymore.
1795–1796	This needs to be conditional on crp != NULL.

Added @asomers since Alan's been looking at GELI stuff. One of the things I changed in the OCF rework was to make GELI use crypto_getreq instead of preallocating space for the crypto requests along with other data it was already allocating. That part could be reverted now to using this API instead and doing fewer allocations. (It's still better than the old OCF bits that needed the crd's as well as the crp).
