[PATCH 5.10.y 1/7] block: remove a dead check in show_partition

[Sasha Levin <sashal@kernel.org>]

From: Christoph Hellwig <hch@lst.de>

[ Upstream commit e3b3bad3f29878d13fdbc96f9e59674bd9b06bae ]

disk_max_parts never returns 0 given that ->minors for devices not using
the extended dev_t must be non-zero, and disk_max_parts always returns
DISK_MAX_PARTS for the latter.
