core: xlator option framework cleanups
- Upon init/reconf, if an option is not in the opt dict,
and a default value is neither specified, null it out.
With this, the xlator config data that comes
out of init/reconf becomes deterministic in terms
of the xlator option declarations and the incoming
option value dictionary. (Needed for correct operation
of volume reset.)
- We can rely bravely on the guarantee given by init/reconf
as of which no NULL value is passed to the converter
functions. Drop the spurious null check of not_null(),
and rebaptize it to pass().
