Subject: [PATCH v3 1/4] remove unneeded comparison

visorchipset_file_cleanup() is called from visorchipset_exit() which
is the module_exit function and this function is executing means
module_init succeeded, so registered will always be true at this time.
and majordev has also been initialized in the init function. hence
these comparisons will always be true.
