Darrick J. Wong 55e45429ce xfs: btree format ifork loader should check for zero numrecs 
A btree format inode fork with zero records makes no sense, so reject it
if we see it, or else we can miscalculate memory allocations.  Found by
zeroes fuzzing {a,u3}.bmbt.numrecs in xfs/{374,378,412} with KASAN.
