maint: use consistent if-else braces in remaining spots 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 all remaining problems, where there weren't enough issues to warrant splitting it further. * src/remote/remote_driver.c (doRemoteOpen): Correct use of {}. * src/security/virt-aa-helper.c (vah_add_path, valid_path, main): Likewise. * src/rpc/virnetsocket.c (virNetSocketNewConnectLibSSH2): Likewise. * src/esx/esx_vi_types.c (esxVI_Type_FromString): Likewise. * src/uml/uml_driver.c (umlDomainDetachDevice): Likewise. * src/util/viralloc.c (virShrinkN): Likewise. * src/util/virbuffer.c (virBufferURIEncodeString): Likewise. * src/util/virdbus.c (virDBusCall): Likewise. * src/util/virnetdev.c (virNetDevValidateConfig): Likewise. * src/util/virnetdevvportprofile.c (virNetDevVPortProfileGetNthParent): Likewise. * src/util/virpci.c (virPCIDeviceIterDevices) (virPCIDeviceWaitForCleanup) (virPCIDeviceIsBehindSwitchLackingACS): Likewise. * src/util/virsocketaddr.c (virSocketAddrGetNumNetmaskBits): Likewise. * src/util/viruri.c (virURIParseParams): Likewise. * daemon/stream.c (daemonStreamHandleAbort): Likewise. * tests/testutils.c (virtTestResult): Likewise. * tests/cputest.c (cpuTestBaseline): Likewise. * tools/virsh-domain.c (cmdDomPMSuspend): Likewise. * tools/virsh-host.c (cmdNodeSuspend): Likewise. * src/esx/esx_vi_generator.py (Type.generate_typefromstring): Tweak generated code.
