Linux 4.11 compat: avoid refcount_t name conflict

Browse Source 
Related to commit 4859fe796, when directly using the kernel's
refcount functions in kernel compatibility code do not map
refcount_t to zfs_refcount_t.  This leads to a type mismatch.

Longer term we should consider renaming refcount_t to
zfs_refcount_t in the zfs code base.
