[docs] [issue16834] ioctl mutate_flag behavior in regard to the buffer size limit

[Yuval Weinbaum]

New submission from Yuval Weinbaum:

In fcntl module, the documentation states the following regarding the mutate_flag in ioctl method:

***
If it is false, the buffer’s mutability is ignored and behaviour is as for a read-only buffer, except that the 1024 byte limit mentioned above is avoided – so long as the buffer you pass is as least as long as what the operating system wants to put there, things should work.
***

However, looking at the code (fcntlmodule.c) it seems that the 1024 bytes limitation is avoided when the mutate_flag is set to True (the opposite of what is stated in the doc).
