x86/pkeys: Clarify PKRU_AD_KEY macro

Browse source

When changing the PKRU_AD_KEY macro to be used for PKS the name came
into question.[1]

The intent of PKRU_AD_KEY is to set an initial value for the PKRU
register but that is just a mask value.

Clarify this by changing the name to PKRU_AD_MASK().

NOTE the checkpatch errors are ignored for the init_pkru_value to align
the values in the code.
