Subject: gdbstub: Prevent fd leakage
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ead75d84cb076d51357ca0a48a2bbaf75e5466f5;p=qemu.git

gdbstub: Prevent fd leakage

Since 2f652224f7, we now check if socket_set_nodelay() errored,
but forgot to close the socket before reporting an error.

Fixes: Coverity CID 1391290 (RESOURCE_LEAK)
