Subject: [PATCH] exfat: remove unnecessary reassignment of
 p_uniname->name_len

kbuild test robot reported :

	fs/exfat/nls.c:531:22: warning: Variable 'p_uniname->name_len'
	is reassigned a value before the old one has been used.

The reassignment of p_uniname->name_len is not needed and remove it.
