Log message:
	Revert 'preserve_pe_start' related code in _text_pv_setup
	
	If pv_setup was given a non-zero pe_start it would short-circuit
	establishing a default pv->pe_align.  pv->pe_align=0 would result
	in a divide by zero in _mda_setup().  'vgconvert -M2 $vgname' hit this.
	
	.pv_write still properly preserves pe_start if it was supplied.
