btrfs: fix unnecessary increment of read error stat on write error
Current btrfs_log_dev_io_error() increases the read error count even if the
erroneous IO is a WRITE request. This is because it forget to use "else
if", and all the error WRITE requests counts as READ error as there is (of
course) no REQ_RAHEAD bit set.
