[PATCH v2] proc/fd: Remove unnecessary {files, f_flags, file} initialization in seq_show()

[Kaitao Cheng]

'files' will be immediately reassigned. 'f_flags' and 'file' will be
overwritten in the if{} or seq_show() directly exits with an error.
so we don't need to consume CPU resources to initialize them.
