spi: loopback-test: Do not split 1024-byte hexdumps
[ Upstream commit a73fa36 ] spi_test_print_hex_dump() prints buffers holding less than 1024 bytes in full. Larger buffers are truncated: only the first 512 and the last 512 bytes are printed, separated by a truncation message. The latter is confusing in case the buffer holds exactly 1024 bytes, as all data is printed anyway. Fix this by printing buffers holding up to and including 1024 bytes in full.
