connect.c: handle errors from split_cmdline
Commit e9d9a8a4d (connect: handle putty/plink also in
GIT_SSH_COMMAND, 2017-01-02) added a call to
split_cmdline(), but checks only for a non-zero return to
see if we got any output. Since the function returns
negative values (and a NULL argv) on error, we end up
dereferencing NULL and segfaulting.
Arguably we could report on the parsing error here, but it's
probably not worth it. This is a best-effort attempt to see
if we are using plink. So we can simply return here with
"no, it wasn't plink" and let the shell actually complain
about the bogus quoting.
