arm64: extable: add new extable type EX_TYPE_KACCESS_ERR_ZERO support
Currently, The extable type EX_TYPE_UACCESS_ERR_ZERO is used by
__get/put_kernel_nofault(), but those helpers are not uaccess type, so we
add a new extable type EX_TYPE_KACCESS_ERR_ZERO which can be used by
__get/put_kernel_no_fault().
This is also to prepare for distinguishing the two types in machine check
safe process.
