staging: ks7010: change length type to unsigned

Browse source 
Length undergoes type conversion when passed (indirectly) as an
argument for parameter of type 'unsigned int'. If length is negative
this is a bug (the value after conversion is large).

Declare 'length' to be an unsigned type instead of a signed type.
