x86/sev: Remove redundant ghcbs_initialized checks around __sev_{get,put}_ghcb()

After

  3645eb7e3915 ("x86/fred: Fix early boot failures on SEV-ES/SNP guests"),

__sev_{get,put}_ghcb() handle the early-boot GHCB fallback internally, making
the ghcbs_initialized guards in __set_pages_state() and
svsm_perform_call_protocol() redundant.

Remove them.

Also initialize state->ghcb to NULL in the early-boot path of
__sev_get_ghcb() so that the ghcb_state is well-defined for all callers,
even though __sev_put_ghcb() currently returns early before reading it.

No functional change intended.
