scsi: sg: Change next_cmd_len handling to mirror upstream

Change the type of next_cmd_len to unsigned char, done in upstream
commit 65c26a0f3969 "sg: relax 16 byte cdb restriction".

Move the range check from sg_write() to sg_ioctl(), which was done by
that commit and commit bf33f87dd04c "scsi: sg: check length passed to
SG_NEXT_CMD_LEN".  Continue limiting the command length to
MAX_COMMAND_SIZE (16).
