Stop init loops
Under certain circumstances, the libcrypto init code would loop,
causing a deadlock. This would typically happen if something in
ossl_init_base() caused an OpenSSL error, and the error stack routines
would recurse into the init code before the flag that ossl_init_base()
had been run was checked.
This change makes sure ossl_init_base isn't run once more of the base
is initiated.
Thanks to Dmitry Kostjuchenko for the idea.
Fixes Github issue #1899
