ksmbd: validate share name from share config response
Share config response may contain the share name without casefolding as
it is known to the user space daemon. When it is present, casefold and
compare it to the share name the share config request was made with. If
they differ, we have a share config which is incompatible with the way
share config caching is done. This is the case when CONFIG_UNICODE is
not set, the share name contains non-ASCII characters, and those non-
ASCII characters do not match those in the share name known to user
space. In other words, when CONFIG_UNICODE is not set, UTF-8 share
names now work but are only case-insensitive in the ASCII range.
