befs driver already has a code which avoids usage of NLS when befs_sb->nls is not set. But befs_fill_super() always set befs_sb->nls, so activating native UTF-8 is not possible. Fix it by not setting befs_sb->nls when iocharset is set to utf8. So now after this cgange mount option iocharset=utf8 activates usage of native UTF-8 code path in befs driver.
