Hi,

I got the following error when trying to run "got fetch" with a "send"
block in got.conf:

    "got: unprivileged process died unexpectedly"

Digged down a bit and found out that got-read-gotconfig is being
terminated with SIGSEGV while trying to free a NULL pointer. That is
caused by "free_send_config" function referencing the global variable
"remote" instead of the its own argument.

This patch fixes "free_send_config" and also "free_fetch_config", which
has the exact same problem.
