qemu_capabilities: Resolve Coverity RESOURCE_LEAK

Browse Source 
In function virQEMUCapsParseMachineTypesStr, VIR_STRNDUP allocates
memory for 'name' in {do,while} loop. If 'name' isn't freed before
'continue', its memory will be allocated again in the next loop.
In this case the memory allocated for 'name' in privious loop is
useless and not freed. Free it before continue this loop to fix that.
