Subject: [PATCH] sm6150-common: mm: Adjust zram write back policy

The first default zram write back time is 3 hours which
is for go device to quickly save more ram. For Pixel
devices, we have more working set and could bring launch
time impact if we write back too fast. Thus, adjust the
first time write back time to 24 hours which is aligned
with periodic write back time.
