Subject: pie: remove unnecessary type casting
Patch-mainline: v5.7-rc1
Git-commit: 220d4ac74ed691033b6fe2bd98dc07d6bdece046
References: jsc#SLE-15172
In function pie_calculate_probability(), the variables alpha and
beta are of type u64. The variables qdelay, qdelay_old and
params->target are of type psched_time_t (which is also u64).
The explicit type casting done when calculating the value for
the variable delta is redundant and not required.
