staging: iio: ad2s1210: remove redundant assignment to variable negative 

Variable negative is being assigned a value that is never read, it is
being re-assigned later. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
drivers/staging/iio/resolver/ad2s1210.c:502:3: warning: Value stored
to 'negative' is never read [deadcode.DeadStores]
