Pull up following revision(s) (requested by kre in ticket #801):
        usr.sbin/sysinst/partman.c: 1.20-1.21
PR install/53220
Don't call pm_lvm_find() unless have_lvm
pm_lvm_find() assumes that data structs (lvms) has been allocated
for it to use, which doesn't happen if !have_lvm
This avoids a sysinst core dump when the lvm command is not installed
(such as when installing from the embedded RAM root filesys in an
INSTALL kernel.)
--
Change return type of pm_lvm_find() from int to void.
It always returns (returned) 0 which was ignored by the one call.
