9pfs: Fix CLI parsing crash on error
Calling error_report() in a function that takes an Error ** argument
is suspicious. 9p-handle.c's handle_parse_opts() does that, and then
fails without setting an error. Wrong. Its caller crashes when it
tries to report the error:
$ qemu-system-x86_64 -nodefaults -fsdev id=foo,fsdriver=handle
qemu-system-x86_64: -fsdev id=foo,fsdriver=handle: warning: handle backend is deprecated
qemu-system-x86_64: -fsdev id=foo,fsdriver=handle: fsdev: No path specified
Segmentation fault (core dumped)
Screwed up when commit 91cda4e8f37 (v2.12.0) converted the function to
Error. Fix by calling error_setg() instead of error_report().
