LU-2734 tests: Remove XXXDEV overrides in init_facets_vars()

init_facets_vars() assigns outputs of xxxdevname() calls to XXXDEVs.
This is incorrect because XXXDEVs are supposed to contain device names
while xxxdevname() calls may print dataset names for ZFS-based facets.
Actually, XXXDEV should not be changed at all.  This patch removes the
XXXDEV assignments.
