crypto: inside-secure/eip93 - acquire lock on eip93_put_descriptor hash

In the EIP93 HASH functions, the eip93_put_descriptor is called without
acquiring lock. This is problematic when multiple thread execute hash
operations.

Correctly acquire ring write lock on calling eip93_put_descriptor to
prevent concurrent access and mess with the ring pointers.
