[PATCH 5.10.y] block: Make REQ_OP_ZONE_FINISH a write operation

[Sasha Levin <sashal@kernel.org>]

From: Damien Le Moal <dlemoal@kernel.org>

[ Upstream commit 3f66ccbaaef3a0c5bd844eab04e3207b4061c546 ]

REQ_OP_ZONE_FINISH is defined as "12", which makes
op_is_write(REQ_OP_ZONE_FINISH) return false, despite the fact that a
zone finish operation is an operation that modifies a zone (transition
it to full) and so should be considered as a write operation (albeit
one that does not transfer any data to the device).

Fix this by redefining REQ_OP_ZONE_FINISH to be an odd number (13), and
redefine REQ_OP_ZONE_RESET and REQ_OP_ZONE_RESET_ALL using sequential
odd numbers from that new value.

Fixes: 6c1b1da58f8c ("block: add zone open, close and finish operations")
