[PATCH] scsi: qedi: remove declaration of nvm_image from stack

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

The nvm_image is a large struct qedi_nvm_iscsi_image object of
over 24K so don't declare it on the stack just for a sizeof
requirement; use sizeof on struct qedi_nvm_iscsi_image instead.

Fixes: c77a2fa3ff8f ("scsi: qedi: Add the CRC size within iSCSI NVM image")
