Currently these fields are protected with the state_lock, but that doesn't really make a lot of sense. These fields are "private" to the nfs4_file, and can be protected with the more granular fi_lock. The fi_lock is already held when setting these fields. Make the code hold the fp->fi_lock when clearing the lease-related fields in the nfs4_file, and no longer require that the state_lock be held when calling into this function. To prevent lock inversion with the i_lock, we also move the vfs_setlease and fput calls outside of the fi_lock. This also sets us up for allowing vfs_setlease calls to block in the future. Finally, remove a redundant NULL pointer check. unhash_delegation_locked locks the fp->fi_lock prior to that check, so fp in that function must never be NULL.
