qcacmn: Modify number of buffers in Relay FS

Bring down number of sub buffers in Relay FS from
470 to 255. Earlier 470 buffers were introduced to
maintain 2MB uniformity across platform for relayfs.
But, as IPQ5018 is 512M platform and having 255
buffers is sufficient enough to hold CFR data,
we have brought down the number to 255.

This saves 1MB memory.

-/* The number 470 has come up by considering the 2MB benchmark

- * For Cypress and pine, since the buffer size has increased

- * CFR records would have been lesser in number (around 130)
- * So, the decision had been taken to keep the sub buffer
- * count to 255 and as result the relay fs buffer pool size

- * In case of Maple, since the Buffer size is small (4470B)
- * we have decided to maintain the relay fs buffer pool size
- * as 2MB, as a result the number of sub buffers has become
