vvfat: create_long_filename: fix out-of-bounds array access
create_long_filename() intentionally uses direntry_t->name[8+3] array
as a larger array. This works, but makes static code analysis tools
unhappy. The problem here is that a directory entry holding long file
name is significantly different from regular directory entry, and the
name is split into several parts within the entry, not just in regular
8+3 name field.
Treat the entry as array of bytes instead. This fixes the OOB access
from the compiler/tools PoV, but does not change the resulting code
in any way.
Keep the existing code style.
