When debugging is enabled and a zfs_refcount_t contains multiple holders using the same key, but different ref_counts, the wrong reference_t may be transferred. Add a zfs_refcount_transfer_ownership_many() function, like the existing zfs_refcount_*_many() functions, to match and transfer the correct refcount_t; This issue may occur when using encryption with refcount debugging enabled. An arc_buf_hdr_t can have references for both the hdr->b_l1hdr.b_pabd and hdr->b_crypt_hdr.b_rabd both of which use the hdr as the reference holder. When unsharing the buffer the p_abd should be transferred. This issue does not impact production builds because refcount holders are not tracked.
