Dmitry V. Levin 92ac6131a1 tests: replace init_magic with fill_memory
Use the same fill_memory/fill_memory_ex interface in all affected tests.

* tests/ioctl_block.c (init_magic): Remove.
(main): Replace init_magic with fill_memory.
* tests/ioctl_evdev.c: Likewise.
* tests/ioctl_v4l2.c: Likewise.
* tests/ioctl_mtd.c (magic, init_magic): Remove.
(main): Replace init_magic with fill_memory.
* tests/ioctl_rtc.c: Likewise.
