regularize emptiness checks in fini_module(2) and vfs_dedupe_file_range()

With few exceptions emptiness checks are done as fd_file(...) in boolean
context (usually something like if (!fd_file(f))...); those will be
taken care of later.

However, there's a couple of places where we do those checks as
'store fd_file(...) into a variable, then check if this variable is
NULL' and those are harder to spot.

Get rid of those now.

use fd_empty() instead of extracting file and then checking it for NULL.
