lib: Fix out-of-bounds write when concatenating commands This commit fixes the hci_commandstostr() command by writing new line character in place of trailing space when wrapping long lines. Previous approach was to append new line character to existing string, which caused buffer overflow when there was more than 9 lines in the output string. Also, the last trailing space is removed in order to return trailing-spaces-free string to the caller.
