iio: invensense: remove redundant initialization of variable period

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]
