This fixes memory leak issues in sd_open function which were brought
by the patch titled "bs_sheepdog.c: support various VDI options in
--backing-store option" (commit:
f282f83c036e298f316ef64d1e51aff3f57b9eaf).
The current sd_open function doesn't free locally allocated string
"orig_filename" nor restores "filename" argument temporarily broken
for parsing VDI options when unknown protocol was specified or tcp
port number was malformed.
