Refactor pvcreate - split pvcreate_validate_params into recovery/non-recovery.

Browse Source 
Split pvcreate_validate_params into recovery and non-recovery parameters.
This is necessary so we can call the non-recovery validate function from
vgextend / vgcreate.  Note in the pvcreate tool case, we must call the
recovery validation function first (see treatment of pe_start and --zero),
and that we add a call to fill_default_pvcreate_params before the validation
functions.
