Miquel Raynal 7821d743ab iio: st_sensors: Add a local lock for protecting odr ...

[ Upstream commit 474010127e2505fc463236470908e1ff5ddb3578 ]

Right now the (framework) mlock lock is (ab)used for multiple purposes:
1- protecting concurrent accesses over the odr local cache
2- avoid changing samplig frequency whilst buffer is running

Let's start by handling situation #1 with a local lock.
