descriptor.c: Read a full config-desc-header on first config-desc read
For some reason the first get config call to determine the total-length
was only reading 8 of the 9 bytes of a full config-desc-header, which
is weird. The Linux kernel reads the full 9 on the first call, so lets
do that in libusb too. Note that for backends which cache the config this
does not matter.
Also check that we've actually gotten back a full header, before parsing it.
