We can't use 'DM_SBIN_PATH'. This one is set only for DM devices but not for all block devices - the pvscan is run on all relevant block devices! This LVM_SBIN_PATH (as well as DM_SBIN_PATH) detection should be removed eventually but for upstream solution, we still have to do that as there are known cases where the binaries are put either in /sbin or /usr/sbin (some installation systems, initrd systems etc.).
