Subject: param: initialize store function to NULL if not available.

param: initialize store function to NULL if not available.

I rebased Kees' 'param: do not set store func without write perm'
on top of my 'params: cleanup sysfs allocation'.  However, my patch
uses krealloc which doesn't zero memory, leaving .store unset.
