LU-9894 lfsck: Print correct lfsck start info

When printing which scan type was started, lfsck iterates
through an array of types and compares the given type to
the types in the array.  Type numbers are a bit mask.

However, LFSCK_TYPES_SUPPORTED and LFSCK_TYPES_DEF are the
full mask, and they are the first in the array.  This means
we always match LFSCK_TYPES_SUPPORTED, which results in
always printing "all" as the type of scan.

Reorder the struct to increasing bit order to fix this.
