rds: rds_rm_zerocopy_callback() use list_first_entry()
rds_rm_zerocopy_callback() uses list_entry() on the head of a list
causing a type confusion.
Use list_first_entry() to actually access the first element of the
rs_zcookie_queue list.
Fixes: 9426bbc6de99 ("rds: use list structure to track information for zerocopy completion notification")
