compiler: mac params: late allocation for cursors.

* share/txr/stdlib/compiler.tl (expand-bind-mac-params):
Allocate the curs gensym only when about to recurse over a
nested parameter list, rather than unconditionally. Otherwise,
we always end up allocating one more gensym than we actually
use, for a lower nesting level that might not be there.
Don't use unwind-protect for returning the cursor variable to
the free-list; it makes no sense to be recovering that since
any exception will be abandoning this function entirely.
