Previously, stinit returned zero even if it fails to set the options.
This patch changes the return value to one if one or more of the options
can't be set for a device if the tape numbers are given on command line.
If no numbers are given, stinit returns zero (as before this patch).
After this change, scripts (udev rules) can more easily detect when
stinit fails.

Add code to set/clear the MT_ST_NO_WAIT option bit for MTSETDRVBUFFER.
The string used in the user interface is 'weof-no-wait'.

I can't find any mention of looking up stinit.def in the current
directory first, at least not since version 0.7. Correct the man page
to mention only `/etc/stinit.def'.
