`struct linker_set execsw_set' was declared as const and pointers in it

Browse Source 
were declared as non-const.  This is backwards (_lkm_exec() changes the
pointers but all the target `struct execsw's are const).  Fixed this
and poisoned related declarations to match and removed the bogus casts
that hid the bug.
