zhili.liu 7200170e88 iio: magnetometer: rm3100: add boundary check for the value read from RM3100_REG_TMRC
commit 792595bab4925aa06532a14dd256db523eb4fa5e upstream.

Recently, we encounter kernel crash in function rm3100_common_probe
caused by out of bound access of array rm3100_samp_rates (because of
underlying hardware failures). Add boundary check to prevent out of
bound access.
