exfat: fix truncated volume labels returned by FS_IOC_GETFSLABEL
exfat_ioctl_get_volume_label() passes uniname.name_len to
exfat_utf16_to_nls() as the output buffer length. However, name_len is
the number of UTF-16 code units, while exfat_utf16_to_nls() expects the
buffer size in bytes.
As a result, volume labels that expand during charset conversion are
truncated.The destination buffer is FSLABEL_MAX bytes long, so pass
its actual size to the conversion helper.
