Nathan Bossart 4372adfa24 Fix possible NULL pointer dereference in GetNamedDSMSegment(). 
GetNamedDSMSegment() doesn't check whether dsm_attach() returns
NULL, which creates the possibility of a NULL pointer dereference
soon after.  To fix, emit an ERROR if dsm_attach() returns NULL.
This shouldn't happen, but it would be nice to avoid a segfault if
it does.  In passing, tidy up the surrounding code.
