Darrick J. Wong 3abb2ac959 ext4: limit entries returned when counting fsmap records 
[ Upstream commit af8c53c8bc087459b1aadd4c94805d8272358d79 ]

If userspace asked fsmap to try to count the number of entries, we cannot
return more than UINT_MAX entries because fmh_entries is u32.
Therefore, stop counting if we hit this limit or else we will waste time
to return truncated results.
