smb: server: Fix extension string in ksmbd_extract_shortname()
commit 8e7d178d06e8937454b6d2f2811fa6a15656a214 upstream.
In ksmbd_extract_shortname(), strscpy() is incorrectly called with the
length of the source string (excluding the NUL terminator) rather than
the size of the destination buffer. This results in "__" being copied
to 'extension' rather than "___" (two underscores instead of three).
Use the destination buffer size instead to ensure that the string "___"
(three underscores) is copied correctly.
