target/i386: fix byte swap issue with XMM register access
During the conversion to the gdb_get_reg128 helpers the high and low
parts of the XMM register where inadvertently swapped. This causes
reads of the register to report the incorrect value to gdb.
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/971
Fixes: b7b8756a9c (target/i386: use gdb_get_reg helpers)
