Describe the bug

Not enough bytes are disassembled in disassembly mode, causing "invalid" instructions to be decoded near the end of the linear disassembly.

To Reproduce

Steps to reproduce the behavior:

1. Open a binary
2. Go to the "Disassembly" mode.
3. Scroll until near the end of the disassembly window you don't start seeing "invalid" instructions. When scrolling back a bit, the invalid instructions will be correctly decoded, but when going back to the previous point they will still be displayed as "invalid"

Expected behavior

Cutter disassembles a bit more bytes than what it does now, so that it can correctly disassemble even longer instructions near the end of the "page".
