fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()
fpga: m10bmc-sec: change contact for secure update driver
fpga_mgr_test_img_load_sgt() allocates memory for sgt using
kunit_kzalloc() however it does not check if the allocation failed.
It then passes sgt to sg_alloc_table(), which passes it to
__sg_alloc_table(). This function calls memset() on sgt in an attempt to
zero it out. If the allocation fails then sgt will be NULL and the
memset will trigger a NULL pointer dereference.
Fix this by checking the allocation with KUNIT_ASSERT_NOT_ERR_OR_NULL().
