virsh.c: Fix compiler warning

For some reason I only get this after applying subsequent upcoming
patches that touch virsh, but don't seem to actually cause the warning.

virsh.c: In function ‘vshCommandParse’:
virsh.c:2014:46: error: ‘opt_index’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
cc1: all warnings being treated as errors
