samples/rpmsg: Replace print_hex_dump() with print_hex_dump_debug()

[ Upstream commit 2519fbb39711e5e6696685f29fe049af93c5987c ]

Replace the raw print_hex_dump() call in the rpmsg_sample_cb() function
with the equivalent print_hex_dump_debug() better suited for dynamic
debug. This switch allows flexibility of controlling this trace through
dynamic debug when enabled.
