mei: me: fix hw ready reset flow

commit b04ada92ffaabb868497a1fce8e4f6bf74e5488f upstream.

We cleared H_RST for H_CSR on spurious interrupt generated when ME_RDY
while cleared and not while  ME_RDY is set. The spurious interrupt
is not delivered on all platforms in this case the
driver may fail to initialize.
