 Log Message:
 nouveau(4): Fix return value of fence wait.
 
 kpause(9) returns EAGAIN/EWOULDBLOCK when it times out, which is
 perfectly normal and expected here with an internal one-tick timeout
 which should just go through another loop iteration.  This function
 is expected to return the number of ticks left to wait when done, so
 it reports timeout by returning zero, and is forbidden to fail with
 EAGAIN/EWOULDBLOCK.
 
 This is also forbidden to fail with EINTR -- on interruption it must
 fail with the Linux ERESTARTSYS instead.  So map EINTR to that too
 while here.
