maint: use hanging curly braces

Our style overwhelmingly uses hanging braces (the open brace
hangs at the end of the compound condition, rather than on
its own line), with the primary exception of the top level function
body.  Fix the few remaining outliers, before adding a syntax
check in a later patch.

* src/interface/interface_backend_netcf.c (netcfStateReload)
(netcfInterfaceClose, netcf_to_vir_err): Correct use of { in
compound statement.
* src/conf/domain_conf.c (virDomainHostdevDefFormatSubsys)
(virDomainHostdevDefFormatCaps): Likewise.
* src/network/bridge_driver.c (networkAllocateActualDevice):
Likewise.
* src/util/virfile.c (virBuildPathInternal): Likewise.
* src/util/virnetdev.c (virNetDevGetVirtualFunctions): Likewise.
* src/util/virnetdevmacvlan.c
(virNetDevMacVLanVPortProfileCallback): Likewise.
* src/util/virtypedparam.c (virTypedParameterAssign): Likewise.
* src/util/virutil.c (virGetWin32DirectoryRoot)
(virFileWaitForDevices): Likewise.
* src/vbox/vbox_common.c (vboxDumpNetwork): Likewise.
* tests/seclabeltest.c (main): Likewise.
