powercap: intel_rapl: remove redundant store to value after multiply

Browse Source 
There is no need to store the result of the multiply back to variable value
after the multiplication. The store is redundant, replace *= with just *.

Cleans up clang scan build warning:
warning: Although the value stored to 'value' is used in the enclosing
expression, the value is never actually read from 'value'
