qcacmn: Remove temp_samp_msg_len and unnecessary updates to it

Remove unused variable temp_samp_msg_len from
target_if_spectral_create_samp_msg(). This variable does get updated,
but is ultimately unused. By removing it, we save processor cycles
which would otherwise be wasted on the update operations occurring for
each Spectral sample.
