	libmultipath   : configure.c structs_vec.c 

Log message:
	Fix for bz 677821.  Multipathd was not aways going into recovery mode when all
	paths went down, and no_path_retry was set to timeout because of two bugs.
	First off, multipathd was always resetting the hardware entry when it was
	updating the multipath device.  This caused problems when no paths were
	available to get the hardware information from.  Second, in one place,
	multipathd forgot to count ghost paths in nr_active paths, this allowed
	nr_active paths to go negative.
