block: make bio_integrity_map_user() static inline

[ Upstream commit 546d191427cf5cf3215529744c2ea8558f0279db ]

If CONFIG_BLK_DEV_INTEGRITY isn't set, then the dummy helper must be
static inline to avoid complaints about the function being unused.

Fixes: fe8f4ca7107e ("block: modify bio_integrity_map_user to accept iov_iter as argument")
