qcacmn: Adjust FFT bin size for Spectral report mode 2

Forráskód böngészése 
On IPQ8074, for report mode 2 only the in-band bins are DMA'ed.
Scatter/gather is used. However, the HW generates all bins, not just
in-band, and reports the number of bins accordingly. The subsystem
arranging for the DMA cannot change this value. The host driver needs
to check if report format is 2, and if so halve the number of bins
reported to get the number actually DMA'ed.
