[nas] (resend) hard hang in libaoss.so

[Paul Fox]

i believe the problem is that if we take an alarm signal while still
in the middle of disableProcessFlow(), we'll call disableProcessFlow()
again.  so rather than clearing the processFlowEnabled flag when we're
finished disabling, we should probably clear it beforehand, as in this
patch.

(i'm not _absolutely_ sure this is a good fix, since i'm debugging
this remotely, on a system at home with no speakers connected, which
isn't the most complete way to debug nasd.  but gdb says it's doing
the right thing.  :-)
