[PATCH] iio: magnetometer: ak8974: remove redundant zero timeout check

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

At the end of the delay loop timeout will always be zero
and hence the check for !timeout will always be true. Remove
the redundant check and the redundant return 0 at the end of
the function.

Fixes CoverityScan CID#1357168 ("Logically dead code")
