Andrew b46b312817 gmnlm: host freed too early, causing UAF 
The host variable is freed too early. If a client certificate is not
found, the later error message in the
GEMINI_STATUS_CLASS_CLIENT_CERTIFICATE_REQUIRED case uses the freed host
variable to produce an incorrect openssl command. This fix just delays
the free to after the switch statement.

Test case:
gmnlm gemini://feeds.drewdevault.com

Prior:
The following OpenSSL command will generate a certificate for this host:

openssl req -x509 -newkey rsa:4096 \
 -keyout /home/andrew/.local/share/gmni/certs/€Ú-=öU.key \
 -out /home/andrew/.local/share/gmni/certs/€Ú-=öU.crt \
 -days 36500 -nodes

Now:
The following OpenSSL command will generate a certificate for this host:

openssl req -x509 -newkey rsa:4096 \
-keyout /home/andrew/.local/share/gmni/certs/feeds.drewdevault.com.key \
-out /home/andrew/.local/share/gmni/certs/feeds.drewdevault.com.crt \
-days 36500 -nodes
