[PATCH 5.15.y 5/8] iio: invensense: remove redundant initialization of variable period

[Sasha Levin <sashal@kernel.org>]

From: Colin Ian King <colin.i.king@gmail.com>

[ Upstream commit b58b13f156c00c2457035b7071eaaac105fe6836 ]

The variable period is being initialized with a value that is never
read, it is being re-assigned a new value later on before it is read.
The initialization is redundant and can be removed.

Cleans up clang scan build warning:
Value stored to 'period' during its initialization is never
read [deadcode.DeadStores]
