[PATCH] zd1211rw: Readd zd_addr_t cast

Robert P.J. Day's recent commit ("getting rid of all casts of k[cmz]alloc()
calls") introduced a sparse warning for zd1211rw, related to our type-checking
of addresses.

	zd_chip.c:116:15: warning: implicit cast to nocast type

This patch readds the type cast, it is correct.
