Revert "drm/amdgpu: add missing size check in amdgpu_debugfs_gprwave_read()"
This reverts commit 25d7e84343e1235b667cf5226c3934fdf36f0df6.
The origin mainline patch fix a buffer overflow issue in
amdgpu_debugfs_gprwave_read(), but it has not been introduced in kernel
6.1 and older kernels. This patch add a check in a wrong function in the
same file.
