Detected by Coverity.

* daemon/remote.c: Calling allocation function 'get_nonnull_domain' to 
  allocate memory to 'dom', but haven't released it in 'cleanup' section.
* src/qemu/qemu_command.c: Taking 'if (!port)' true branch then 'def = NULL',
  the codes jump into 'error' section, the function 'virDomainDefFree(def)'
  willn't release it.
* src/remote/remote_driver.c: Calling allocation function 'get_nonnull_domain' to
  allocate memory to 'dom', but haven't released it in 'no_memory' section.
* src/util/pci.c: Calling allocation function 'pciGetVirtualFunctions' on 
  'virt_fns', but haven't released it in 'out' section.
* src/vmx/vmx.c: Calling allocation function 'virConfReadMem' to allocate
  memory to 'conf' and then taking 'if (VIR_ALLOC(def) < 0)' true branch,
  the codes haven't released it before 'return NULL'.
