gdbstub: i386: Fix gdb_get_reg16() parameter to unbreak gdb
We should only pass in gdb_get_reg16() with the GByteArray* object
itself, no need to shift. Without this patch, gdb remote attach will
crash QEMU:
(gdb) target remote :1234
Remote debugging using :1234
Remote communication error. Target disconnected.: Connection reset by peer.
$ qemu-system-x86_64 -m 1G -smp 4 ... -s
ERROR:qemu/gdbstub.c:1843:handle_read_all_regs: assertion failed: (len == gdbserver_state.mem_buf->len)
Bail out! ERROR:qemu/gdbstub.c:1843:handle_read_all_regs: assertion failed: (len == gdbserver_state.mem_buf->len)
Fixes: a010bdbe719 ("extend GByteArray to read register helpers")
