[libvirt] [PATCHv2] python: Fix problems of virDomain{Set, Get}BlkioParameters bindings

[ajia at redhat.com]

From: Alex Jia <ajia at redhat.com>

The parameter 'device_weight' is a string, however, the 'VIR_TYPED_PARAM_STRING'
type condition is missed by libvirt_virDomain{Set, Get}BlkioParameters bindings,
the result is we can't get or change 'device_weight' value.

* python/libvirt-override.c: Add missing 'VIR_TYPED_PARAM_STRING' condition into
libvirt_virDomain{Set, Get}BlkioParameters bindings and free allocated memory.
