pvchange: fix exit code regression

Browse Source 
Commit 1a832398a7 moved
some code from _pvchange_single() to main pvchange() and
introduced exit code regression as return codes have not
been properly changed, thus pvchange command exited
with '0' exit code, even though it has reported error.
Also there is a missing vg unlock in error path.

Fix it by counting the total number of expected calls before
checking for pvname and also unlock and relase vg when
pv is not found.
