ksmbd: fix permission checks for file allocation ioctls

FSCTL_SET_SPARSE should not require FILE_WRITE_ATTRIBUTES only. A handle
with FILE_WRITE_DATA or FILE_APPEND_DATA is also allowed to set the file
allocation state, while FILE_WRITE_EA alone must still be rejected.

FSCTL_QUERY_ALLOCATED_RANGES needs FILE_READ_DATA access. Reject handles
that only have metadata access such as FILE_READ_ATTRIBUTES.
