jffs2: Remove calls to set/clear the folio error flag

Browse Source 
Nobody checks the error flag on jffs2 folios, so stop setting and
clearing it.  We can also remove the call to clear the uptodate
flag; it will already be clear.

Convert one of these into a call to mapping_set_error() which will
actually be checked by other parts of the kernel.
