scst_vdisk, MODE SELECT(10): Interpret both bytes of the BLOCK DESCRIPTOR LENGTH field

Browse Source 
While the BLOCK DESCRIPTOR LENGTH field spans a single byte in the
Mode parameter header(6), the size of this field in the Mode parameter
header(10) is two bytes. Interpret both bytes while executing a MODE
SELECT(10) command.
