staging: unisys: visorhba: fix s-Par to boot with option CONFIG_VMAP_STACK set to y
[ Upstream commit 3c2bf0bd08123f3497bd3e84bd9088c937b0cb40 ]
The root issue is that we are not allowed to have items on the
stack being passed to "DMA" like operations. In this case we have
a vmcall and an inline completion of scsi command.
This patch fixes the issue by moving the variables on stack in
do_scsi_nolinuxstat() to heap memory.
