SSL: fixed compression workaround to remove all methods.

Previous code used sk_SSL_COMP_delete(ssl_comp_methods, i) while iterating
stack from 0 to n, resulting in removal of only even compression methods.

In real life this change is a nop, as there is only one compression method
which is enabled by default in OpenSSL.
