Subject: [PATCH] journald: remove rotated file from hashmap when rotation
 fails

Before, when the user journal file was rotated, journal_file_rotate
could close the old file and fail to open the new file. In that
case, we would leave the old (deallocated) file in the hashmap.
On subsequent accesses, we could retrieve this stale entry, leading
to a segfault.

When journal_file_rotate fails with the file pointer set to 0,
old file is certainly gone, and cannot be used anymore.
