LU-3020 obdclass: Lustre returns EINTR when SA_RESTART is set
When Lustre is in a read or write system call and receives a
SIGALRM, it currently returns EINTR at this location. This is
problematic because it prevents the system call from being restarted
if SA_RESTART is set in the handler.
This patch changes behavior in this location to return ERESTARTSYS
when a signal is found.
