Logan Gunthorpe e38b043255 md/raid5: Annotate rdev/replacement accesses when nr_pending is elevated 
There are a number of accesses to __rcu variables that should be safe
because nr_pending in the disk is known to be elevated.

Create a wrapper around rcu_dereference_protected() to annotate these
accesses and verify that nr_pending is non-zero.

This fixes a number of sparse warnings.
