[linux-lvm] [PATCH LVM2] (2/3) use _for_each_pv() from _check_contiguous()

[Jun'ichi Nomura]

This patch rewrites _check_contiguous() to use _for_each_pv().

_for_each_pv() is a generic iterator function to execute given
function on each PV constituting the specified range of LV.
Since _check_contiguous() tries to find contiguous PV segment from
the end of the existing LV segment, I gave the last one LE as
a iteration range of _for_each_pv().

To pass necessary parameters to _for_each_pv callback (_match_pv()),
this patch adds new struct pv_match_handle.

The patch doesn't fix any bug but is a preparation for later patch.
Also, the use like this is what _for_each_pv() is intended for, I think.
