Marek Szyprowski 27afd6e066 media: videobuf2: forbid remove_bufs when legacy fileio is active ...

vb2_ioctl_remove_bufs() call manipulates queue internal buffer list,
potentially overwriting some pointers used by the legacy fileio access
mode. Forbid that ioctl when fileio is active to protect internal queue
state between subsequent read/write calls.
