This reverts commit 4ddf3215a7df3ac4a0cfceccb283414510078ba5.
Fix T70991 - File Explorer: Maximize window no the filename textbox on Windows
Note, although this fix the immediate obvious issue there are still some
things that need fixing in this file browser.
For instance, now (or before this commit) Blender stores the maximized
window size but not its state. So if you re-open the file browser after
maximizing it, the window will be very big although not "maximized".
Also the file browser is always opened in the top edge of the window,
regardless of where it was moved to last time (unlike the console window
or the view render for example).
So we should decide and be consistent. We either NEVER save either
parameter, or save them all.
