Subject: [PATCH 53/56] block: Don't call no_coroutine_fns in
qmp_block_resize()
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 164: block: Fix hangs in qmp_block_resize()
RH-Bugzilla: 2185688

RH-Commit: [2/4] 7ac7e34821cfc8bd5f0daadd7a1c4a5596bc60a6 (kmwolf/centos-qemu-kvm)
This QMP handler runs in a coroutine, so it must use the corresponding
no_co_wrappers instead.
