[XFS] Long btree pointers are still 64 bit on disk On 32 bit machines with CONFIG_LBD=n, XFS reduces the in memory size of xfs_fsblock_t to 32 bits so that it will fit within 32 bit addressing. However, the disk format for long btree pointers are still 64 bits in size. The recent btree rewrite failed to take this into account when initialising new btree blocks, setting sibling pointers to NULL and checking if they are NULL. Hence checking whether a 64 bit NULL was the same as a 32 bit NULL was failingi resulting in NULL sibling pointers failing to be detected correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns in xfs_btree_delrec. Fix this by making all the comparisons and setting of long pointer btree NULL blocks to the disk format, not the in memory format. i.e. use NULLDFSBNO.
