[PATCH] drm/i915/perf: remove redundant variable 'taken'

[Colin Ian King]

The assignment to variable taken is redundant and so it can be
removed as well as the variable too.

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