drm/amdgpu: validate RAS EEPROM tbl_size before record count

Corrupt EEPROM data can set tbl_size below the table header size.
Guard the RAS_NUM_RECS macros against undersized tbl_size and reset
the table during init when tbl_size is below the minimum for the table
version instead of trusting the header.
