xfs: always scrub record/key order of interior records

Browse source

In commit d47fef9342, we removed the firstrec and firstkey fields of
struct xchk_btree because Christoph thought they were unnecessary
because we could use the record index in the btree cursor.  This is
incorrect because bc_ptrs (now bc_levels[].ptr) tracks the cursor
position within a specific btree block, not within the entire level.

The end result is that scrub no longer detects situations where the
rightmost record of a block is identical to the leftmost record of that
block's right sibling.  Fix this regression by reintroducing record
validity booleans so that order checking skips *only* the leftmost
record/key in each level.
