[PATCH 5.18 0469/1095] wifi: p54: add missing parentheses in p54_flush()

From: Greg Kroah-Hartman

[ Upstream commit bcfd9d7f6840b06d5988c7141127795cf405805e ]

The assignment of the value to the variable total in the loop
condition must be enclosed in additional parentheses, since otherwise,
in accordance with the precedence of the operators, the conjunction
will be performed first, and only then the assignment.

Due to this error, a warning later in the function after the loop may
not occur in the situation when it should.
