mtd: nand: remove 'sndcmd' parameter of 'read_oob/read_oob_raw'

Browse source 
As of [mtd: nand: remove autoincrement 'sndcmd' code], the
NAND_CMD_READ0 command is issued unconditionally.

Thus, read_oob/read_oob_raw's 'sndcmd' argument is no longer needed, as
well as their return code.

Remove the 'sndcmd' parameter, and set the return code to 0.
