[PATCH] fbcon: Fix endian bug in fbcon_putc (console mouse problem)

The typecast (const unsigned short *) &c in fbcon_putc is not correct for
big-endian machines.  This problem manifests as a black cursor that can be
used to erase the console screen contents.  The correct fix is to use
scr_writew instead.
