drm/amdgpu: fix a signedness bug in __verify_ras_table_checksum()
If amdgpu_eeprom_read() returns a negative error code then the error
handling checks:
if (res < buf_size) {
The problem is that "buf_size" is a u32 so negative values are type
promoted to a high positive values and the condition is false. Fix
this by changing the type of "buf_size" to int.
