UBIFS: switch to RO mode after synchronizing
In 'ubifs_garbage_collect()' on error path, we first switch to R/O mode, and then synchronize write-buffers (to make sure no data are lost). But the GC write-buffer synchronization will fail, because we are already in R/O mode. This patch re-orders this and makes sure we first synchronize the write-buffer, and then switch to R/O mode.
