Delete the __FD_*() functions for operating on fd_set structs from linux/time.h as they're no longer used within the kernel with the preceding patch and are not exported to userspace. Whilst linux/time.h *does* export the FD_*() equivalents as wrappers around __FD_*(), userspace provides its own definition of __FD_*(). Note that the definition of FD_ZERO() in linux/time.h may not be used with the fd_sets associated with struct fdtable as the fd_set may have been allocated in a truncated fashion.
