In other words, it would call `memcpy` with the source parameter being
NULL, which is [explicitly said to be undefined
behavior](https://www.imperialviolet.org/2016/06/26/nonnull.html).

Fix UB in print_expr_str

clang 16 with ASAN and UBSAN flag this as UB because it's performing
pointer arithmetic on a NULL pointer, which is not allowed in C.

I'm getting this on Fedora 38 and on Arch, but for some reason I cannot
seem to hit the original issue on NixOS. Strange, but it's an UB anyway.

tree data BUGFIX don't send null argument into strncmp
98b5653 
The recent patch was sending a NULL pointer to ly_strncmp which passed
the NULL to strncmp. However, strncmp arguments are attributed as
nonnull which make undefined behaviour sanitizer unhappy.

This ubsan report appeared when running sysrepo tests:

  /build/libyang/src/ly_common.c:114:30: runtime error: null pointer passed as argument 2, which is declared to never be null
