Roger Pau Monné b5ba8a0f32 dev/xenstore: fix return with locks held
Fix returning from xenstore device with locks held, which triggers the
following panic:

# cat /dev/xen/xenstore
^C
userret: returning with the following locks held:
exclusive sx evtchn_ringc_sx (evtchn_ringc_sx) r = 0 (0xfffff8000650be40) locked @ /usr/src/sys/dev/xen/evtchn/evtchn_dev.c:262

Note this is not a security issue since access to the device is
limited to root by default.
