Don't remove pack from pack list for problems which could be transient
If we hit a corrupt object or invalid pack remove the pack from the pack
list. Other IOException could be transient hence we should not remove
the pack from the list to avoid the problem reported on the Gerrit list
[1]. It looks like in the reported case the pack was removed from the
pack list causing MissingObjectExceptions which disappear when the
server is restarted.
