[PATCH v2] test/member: fix incorrect expression

[Leyi Rong]

Fix incorrect expression by cast division operand to type double
to match ceil() and fabs() definitions.

Coverity issue: 381398, 381401, 381402
Fixes: db354bd2e1f8 ("member: add NitroSketch mode")

Signed-off-by: Leyi Rong <leyi.rong at intel.com>

v2:
- resubmit as v1 performance CI fail maybe false-positive.
