conf/domain_addr.c: use g_autofree in strings

Use g_autofree in strings when possible to spare a VIR_FREE()
call. Unneeded 'cleanup' labels will be taken care of in the
next patch.

The 'str' string in virDomainVirtioSerialAddrReserve() was
never used by the logic, only being used in cleanup by
VIR_FREE(). Let's remove it.
