wifi: mt76: mt7996: fix overflows seen when writing limit attributes

Browse source

[ Upstream commit 5adbc8ce5b ]

DIV_ROUND_CLOSEST() after kstrtoul() results in an overflow if a large
number such as 18446744073709551615 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.
This commit was inspired by commit: 57ee12b6c5.
