wireless/lpwan/rn2xx3: Fix invalid sync word bug.

linguini1 · Alan C. Assis · commit 0cb7bd7f7625 · 2025-04-20T16:55:45.000-03:00
This commit resolves issue #16009, where a sync word of less than 64 bytes was printed as 0-padded hex. 0-padding is invalid for the RN2xx3 modules, so now it has been removed. Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
