Subject: iio: tmp006: Check channel info on write

From: Peter Meerwald <pmeerw@pmeerw.net>

commit 8d05abfaeff52bdf66aba3a3a337dcdbdb4911bf upstream.

only SAMP_FREQ is writable

Will lead to SAMP_FREQ being written by any attempt to write
to the other exported attributes and hence a rather unexpected
result!
