drm/amdgpu: Disable ras_check_bad_page_status on VFs

Browse Source 
Host driver determines the bad_page_status, not VF.
VFs do not have access to the EEPROM, and eeprom_init
is skipped. However, check_bad_page_status is called
outside of the eeprom_init sequence without any is_vf checks.

Add a return false in __is_ras_eeprom_supported for VFs, and use
that guard in amdgpu_ras_check_bad_page_status to prevent
incorrect access to un-initialized eeprom_control object.
