[Xen-devel] [PATCH] libxl: dispose libxl_dominfo after libxl_domain_info()

[Joao Martins <joao.m.martins@xxxxxxxxxx>]

As suggested in a previous thread [0] this patch adds some missing calls
to libxl_dominfo_dispose when doing some of the libxl_domain_info
operations which would otherwise lead to memory leaks.
