Check return from nxsem_wait_uninterruptible()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is for all remaining drivers in the LC823450 architectures.
