CLEANUP: fd: get rid of the __GET_{NEXT,PREV} macros
They were initially made to deal with both the cache and the update list
but there's no cache anymore and keeping them for the update list adds a
lot of obfuscation that is really not desired. Let's get rid of them now.
Their purpose was simply to get a pointer to fdtab[fd].update.{,next,prev}
in order to perform atomic tests and modifications. The offset passed in
argument to the functions (fd_add_to_fd_list() and fd_rm_from_fd_list())
was the offset of the ->update field in fdtab, and as it's not used anymore
it was removed. This also removes a number of casts, though those used by
the atomic ops have to remain since only scalars are supported.
