Off-by-one in zap_leaf_array_create()
Trying to set user properties with their length 1 byte shorter than the
maximum size triggers an assertion failure in zap_leaf_array_create():
panic[cpu0]/thread=ffffff000a092c40:
assertion failed: num_integers * integer_size < (8<<10) (0x2000 < 0x2000), file: ../../common/fs/zfs/zap_leaf.c, line: 233
