[Intel-gfx] [PATCH i-g-t] tests/kms_fbc_crc: fix fread() return value assertion

[Thomas Wood]

Use 1 as the element size to check the number of bytes returned is
greater than 0, rather than checking the number of elements returned.

This fixes a regression from commit 47f6b13 (igt.cocci: check the
return values of various functions).
