[PATCH v2 5/8] ata: libata-core: Quirk DELLBOSS VD max_sectors

[Niklas Cassel <cassel@kernel.org>]

Commit 9b8b84879d4a ("block: Increase BLK_DEF_MAX_SECTORS_CAP") increased
the default max_sectors_kb from 1280 KiB to 4096 KiB.

DELLBOSS VD with FW rev MV.R00-0 times out when sending I/Os of size
4096 KiB.

Enable ATA_QUIRK_MAX_SEC, with value 8191 (sectors) for this device,
since any I/O with more sectors than leads to I/O timeouts.

With this, the DELLBOSS VD SATA controller is usable again.
