brings back the removed If statement and adds the num_level test

This resolves the out of bounds read/writes in the linear swizzler, it brings back the scaled TOTK Recall bug however, pending further work in the block size calculation.

Recall is not glitched in the Dynamic FPS resolution mod to the degree that it is in the native yuzu scaler, this can be a workaround for the time being.


The recall effect is constructed from multiple 320x180 texture slices, it breaking may have a similar origin to https://github.com/Ryujinx/Ryujinx/pull/5640

but it may also be connected to the other deficiencies identified in the Yuzu size calculations, such as no apparent implementation of slice testing for end of slce depth as opposed to full aligned size as implemented in https://github.com/Ryujinx/Ryujinx/pull/5220
