ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING and ME_IO_STREAM_CONFIG_WRAPAROUND both
hanve 0 as the rightmost bit, and thus eg
!flags & ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING is always 0.
I assume that !(flags & ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING) and
!(flags & ME_IO_STREAM_CONFIG_WRAPAROUND) were intended.

This eliminates checkpatch.pl warnings, that struct file_operations is
usually const. The structs me4000_ai_fops_array and
me4000_ao_fops_array are not modified and thus also made const.

Add a mutex to block ioctls before the card is fully initialised and
only allow one ioctl at a time.
This stops udev trying to load the firmware before to card is fully up.
