staging: axis-fifo: Remove read/write timeout module parameters

Browse source

Module parameters for timeouts are a poor interface choice as they
affect all device instances globally rather than being configurable
per file descriptor.

The current implementation also returns -EAGAIN on timeout, requiring
userspace to implement retry loops around blocking operations.

Remove the read_timeout and write_timeout module parameters. The next
commit adds poll() support, allowing applications to implement timeout
handling using standard poll()/select() interfaces.
