vfs: fs_context: fix up param length parsing in legacy_parse_param
commit 722d94847de29310e8aa03fcbdb41fc92c521756 upstream.
The "PAGE_SIZE - 2 - size" calculation in legacy_parse_param() is an
unsigned type so a large value of "size" results in a high positive
value instead of a negative value as expected. Fix this by getting rid
of the subtraction.
