Even Rouault af76000771 tiftoimage(): fix read heap buffer overflow (#988)
The number of components is given only by TIFFTAG_SAMPLESPERPIXEL / tiSpp.
Querying TIFFTAG_EXTRASAMPLES only give information about which channel is
the alpha channel, but we mostly ignore it for now, so remove that part of the
code.
