Rodrigo Siqueira 16dd2825c2 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]
[   27.804788] Read of size 1 at addr ffff8881647fdb00 by task systemd-udevd/383

...

[   27.821207] Memory state around the buggy address:
[   27.821215]  ffff8881647fda00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

[   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.
