[PATCH v3 1/2] Staging: rts5208: Replace strncpy() with strscpy()

[Nancy Nyambura]

Warning found by checkpath.pl
I replaced strncpy with strscpy because strscpy is suitable when the destination buffer is NUL-terminated, which is often the case when copying strings. Strscpy ensures that the destination buffer is properly NUL-terminated without padding. In the code, the objective is to copy a string (inquiry_string) to the buf buffer, and it's likely that the buf buffer is NUL-terminated since it is handling a string. Strscpy_pad is used when you have afixed-size buffer, and you want to copy a string into it while ensuring the remaining space is padded with a specific character (like '\0') hence not appropriate for this context.
