[PATCH] Revert "scsi: core: Cap scsi_host cmd_per_lun at can_queue"

[Tim Gardner]

BugLink: https://bugs.launchpad.net/bugs/1940564

This reverts commit ce0da9f6062f460c27a7fe6e566c330991e757d8.
(upstream commit dcb634e434b850287b31a117637cbf598563ce1c)

This patch causes boot failures on instances with large numbers
of CPUs and SCSI LUNs, the product of which overflows a 16 bit
quantity. To date, that combination exists in Azure instance
types Standard_M416s_v2 and Azure Standard_D48_v3.
