osmosdr/rtl/miri/hackrf: use 15 buffers by default
folowing rtl-sdr commit 89f73b183f2dac9c0dd75beca4cf2f77f20c4a36
So far we had 32 * 256KB which was a bit overkill, 15 are more than
enough.
15 was chosen instead of 16 because at least on Linux there seems to be
a system-wide limit of 63 transfers (when they are 256KB large), so 4
dongles can be used on a single machine without lowering the default
transfer number.
