Only free qsb that qemu_bufopen allocated, and also allow
qemu_bufopen accept qsb as input for write operation. It
will make the API more logical:
1.If you create the QEMUSizedBuffer yourself, you need to
free it by using qsb_free() but not depends on other API
like qemu_fclose.
2.allow qemu_bufopen() accept QEMUSizedBuffer as input for
write operation, otherwise, it will be a little strange
for this API won't accept the second parameter.
This brings API change, since there are only 3
users of this API currently, this change only impact the
first one which will be fixed in patch 2 of this patchset,
so I think it is safe to do this change.
