uuid: Make qemu_uuid_bswap() take and return a QemuUUID
Currently qemu_uuid_bswap() takes a pointer to the QemuUUID to
be byte-swapped. This means it can't be used when the UUID
to be swapped is in a packed member of a struct. It's also
out of line with the general bswap*() functions we provide
in bswap.h, which take the value to be swapped and return it.
Make qemu_uuid_bswap() take a QemuUUID and return the swapped version.
This fixes some clang warnings about taking the address of
a packed struct member in block/vdi.c.
