nvme-auth: convert dhchap_auth_list to an array
We know exactly how many dhchap contexts we will need, there is no need
to hold a list that we need to protect with a mutex. Convert to
a dynamically allocated array. And dhchap_context access state is
maintained by the chap itself.
Make dhchap_auth_mutex protect only the ctrl host_key and ctrl_key
in a fine-grained lock such that there is no long lasting acquisition
of the lock and no need to take/release this lock when flushing
authentication works.
