hwmon: (hs3001) remove redundant store on division

Currently the local variable hum is being divided by a constant and
the results is being re-assigned back to hum before the value is being
returned to the caller. The assignment to hum is redundant and can
be removed.

Cleans up clang scan build warning:
drivers/hwmon/hs3001.c:65:9: warning: Although the value stored to 'hum'
is used in the enclosing expression, the value is never actually read
from 'hum' [deadcode.DeadStores]
