[libvirt] [PATCH 4/6] maint: use consistent if-else braces in lxc, vbox, phyp



I'm about to add a syntax check that enforces our documented
HACKING style of always using matching {} on if-else statements.

This patch focuses on drivers that had several issues.

* src/lxc/lxc_fuse.c (lxcProcGetattr, lxcProcReadMeminfo): Correct
use of {}.
* src/lxc/lxc_driver.c (lxcDomainMergeBlkioDevice): Likewise.
* src/phyp/phyp_driver.c (phypConnectNumOfDomainsGeneric)
(phypUUIDTable_Init, openSSHSession, phypStoragePoolListVolumes)
(phypConnectListStoragePools, phypDomainSetVcpusFlags)
(phypStorageVolGetXMLDesc, phypStoragePoolGetXMLDesc)
(phypConnectListDefinedDomains): Likewise.
* src/vbox/vbox_common.c (vboxAttachSound, vboxDumpDisplay)
(vboxDomainRevertToSnapshot, vboxDomainSnapshotDelete): Likewise.
* src/vbox/vbox_tmpl.c (vboxStorageVolGetXMLDesc): Likewise.
