[PATCH] x86/resctrl: remove redundant assignment to variable chunks

[Colin Ian King <colin.i.king@gmail.com>]

The variable chunks is being shifted right and re-assinged the shifted
value which is then returned. Since chunks is not being read afterwards
the assignment is redundant and the >>= operator can be replaced with a
shift >> operator instead.
