Mikulas Patocka aa9ee4b1ed dm integrity: fix deadlock with overlapping I/O 
commit 4ed319c6ac08e9a28fca7ac188181ac122f4de84 upstream.

dm-integrity will deadlock if overlapping I/O is issued to it, the bug
was introduced by commit 724376a04d ("dm integrity: implement fair
range locks").  Users rarely use overlapping I/O so this bug went
undetected until now.

Fix this bug by correcting, likely cut-n-paste, typos in
ranges_overlap() and also remove a flawed ranges_overlap() check in
remove_range_unlocked().  This condition could leave unprocessed bios
hanging on wait_list forever.

Cc: stable@vger.kernel.org # v4.19+
Fixes: 724376a04d ("dm integrity: implement fair range locks")
