lib/crypto: md5: Provide functions for zeroizing hmac_md5 structures
In certain cases crypto code functions need to zeroize their local
hmac_md5_key or hmac_md5_ctx structures after use to avoid leaking
sensitive material on the stack.
Provide hmac_md5_zeroize_key() and hmac_md5_zeroize_ctx() helper
functions that e.g. can be used with __cleanup() to automatically
zeroize the structure when it goes out of scope.
While we're at it, replace the related memzero_explicit() call in
lib/crypto/md5.c with a call to the new helper function.
