drm/atmel-hlcdc: check stride values in the first plane
The statement always evaluates to true since the struct fields
are arrays. This has shown up as a warning when compiling with
clang:
warning: address of array 'desc->layout.xstride' will always
evaluate to 'true' [-Wpointer-bool-conversion]
Check for values in the first plane instead.
