drm/amd/display: Adjust VSDB parser for replay feature

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Adjust VSDB parser for replay feature

At some point, the IEEE ID identification for the replay check in the
AMD EDID was added. However, this check causes the following
out-of-bounds issues when using KASAN:

[   27.804016] BUG: KASAN: slab-out-of-bounds in amdgpu_dm_update_freesync_caps+0xefa/0x17a0 [amdgpu]

[   27.821268] ==================================================================

This is caused because the ID extraction happens outside of the range of
the edid lenght. This commit addresses this issue by considering the
amd_vsdb_block size.
