pvcreate: clean up opening and filtering of args

The args for pvcreate/pvremove (and vgcreate/vgextend
when applicable) were not efficiently opened, scanned,
and filtered.  This change reorganizes the opening
and filtering in the following steps:

- label scan and filter all devs
  . open ro
  . standard label scan at the start of command

- label scan and filter dev args
  . open ro
  . uses full md component check
  . typically the first scan and filter of pvcreate devs

- close and reopen dev args
  . open rw and excl

- repeat label scan and filter dev args
  . using reopened rw excl fd

- wipe and write new headers
  . using reopened rw excl fd
