Do not handle device as suspended on error.

Browse Source 
Consider device is suspended only if dm_status_suspended return code
is true.

This function returned -EEXIST for dm devices with target types unknown
to libcryptsetup (for example dm-cache) and turned off O_DIRECT flag
for devices unexpectedly.

Turned out ignoring direct-io was a problem after all :).

Fixes: 0f51b5bacb (Do not run sector read check on suspended device.)
