scst: Unbreak the build for kernel versions <= 6.3

The previous series of patches introduced the use of a const pointer to
scsi_host_template. However, scsi_host_alloc() uses a non-const pointer
prior to kernel version 6.4, causing the build to throw the following
error:

    passing argument 1 of ‘scsi_host_alloc’ discards ‘const’
    qualifier from pointer target type

Hence, cast away the constness to resolve the error.
