qcom: nand: fix NAND dummy spare area programming

Browse source 
NAND_CMD_PRG_PAGE_ALL uses the spare data from buffer itself
which is not applicable. The spare area in NAND page for
QPIC are dummy bytes so 0xff should be written to these
spare area. NAND_CMD_PRG_PAGE does the same thing and HLOS
driver uses this command for all page program
operations.  The actual spare data is being written along
with every codeword since the codewords size is 516 in which
512 bytes are user data and 4 bytes are spare data.
