[PATCH][next] vboxsf: remove redundant variable out_len

[Colin Ian King <colin.i.king@gmail.com>]

The variable out_len is being used to accumulate the number of
bytes but it is not being used for any other purpose. The variable
is redundant and can be removed.

Cleans up clang scan build warning:
fs/vboxsf/utils.c:443:9: warning: variable 'out_len' set but not
used [-Wunused-but-set-variable]
