[PATCH] searchidx: v1: fix retries when Xapian and Msgmap are out-of-sync

[Eric Wong <e@yhbt.net>]

We forcibly stop git-log here, so erroring out on git-log close
failures is wrong since it sees SIGPIPE.  Noticed while
reindexing a large v1 inbox for IMAP changes.

Fixes: b32b47fb12a3043d ("index: "git log" failures are fatal")
