Revert "drm/amd/display: reduce stack for dml32_CalculateVMRowAndSwath"

This reverts commit 0b6549a6dfb8b9fc689353dede6abc60349f784f.

This commit was a part of a patchset responsible for reducing the stack
size. However, after some other changes, this commit becomes
unnecessary, so we are reverting it here.
