Subject: [PATCH] atm: clean up vcc_seq_next()

From: Dan Carpenter <[email-masked]>

It's confusing to call PTR_ERR(v).  The PTR_ERR() function is basically
a fancy cast to long so it makes you wonder, was IS_ERR() intended?  But
that doesn't make sense because vcc_walk() doesn't return error
pointers.

This patch doesn't affect runtime, it's just a cleanup.
