lv_manip: check fs resize is supported before LV extension

This avoids a situation where we would extend an LV and then we would
not do anything to the FS on it because the FS info check failed for some
reason, like the type was not supported (e.g. swap) or we could not resize
the FS unless being in some supported state (e.g. XFS to be mounted for
the xfs_growfs to work).

Before this patch (LV resized, FS not resized):

❯  lvextend --fs resize -L+4M vg/swap
  Size of logical volume vg/swap changed from 32.00 MiB (8 extents) to 36.00 MiB (9 extents).
  File system extend is not supported (swap).
  File system extend error.
  Logical volume vg/swap successfully resized.

With this patch (LV not resized, FS not resized):

❯  lvextend --fs resize -L+4M vg/swap
  File system extend is not supported (swap).
