Yunseong Kim dcfd255732 crypto: ccp - Fix incorrect payload size calculation in psp_poulate_hsti() 
[ Upstream commit 2b0dc40ac6 ]

payload_size field of the request header is incorrectly calculated using
sizeof(req). Since 'req' is a pointer (struct hsti_request *), sizeof(req)
returns the size of the pointer itself (e.g., 8 bytes on a 64-bit system),
rather than the size of the structure it points to. This leads to an
incorrect payload size being sent to the Platform Security Processor (PSP),
potentially causing the HSTI query command to fail.

Fix this by using sizeof(*req) to correctly calculate the size of the
struct hsti_request.
