Subject: gdbstub: init mon_chr through qemu_chr_alloc
X-Git-Tag: v2.1.3~81

gdbstub: init mon_chr through qemu_chr_alloc

This patch initializes monitor for gdbstub with the qemu_chr_alloc function
instead of just allocating the memory. Initialization function call
is required, because it also creates chr_write_lock mutex, which is used
when writing to this character device.
