dm suspend: return -ERESTARTSYS instead of -EINTR
[ Upstream commit 1e1fd567d32fcf7544c6e09e0e5bc6c650da6e23 ]
This commit changes device mapper, so that it returns -ERESTARTSYS
instead of -EINTR when it is interrupted by a signal (so that the ioctl
can be restarted).
The manpage signal(7) says that the ioctl function should be restarted if
the signal was handled with SA_RESTART.
