[PATCH] rdma: siw: remove unused variable

[Anders Roxell]

The variable 'p' si no longer used and the compiler rightly complains
that it should be removed.

../drivers/infiniband/sw/siw/siw_mem.c: In function ‘siw_free_plist’:
../drivers/infiniband/sw/siw/siw_mem.c:66:16: warning: unused variable
 ‘p’ [-Wunused-variable]
  struct page **p = chunk->plist;
                ^

Rework to remove unused variable.

Fixes: 8288d030447f ("mm/gup: add make_dirty arg to 
put_user_pages_dirty_lock()")
