Fix assertion checks in libs/hwui/Mesh.cpp

The original code contained assertions that checked `fICount` and `fIOffset`, which seem to be mistakenly copied from the Skia codebase. This commit corrects the assertions to properly reflect the variables used in the AOSP codebase, updating them to `mIndexCount` and `mIndexOffset` as intended. The correction ensures accurate runtime checks for the expected conditions and prevents compilation error due to undeclared identifier.
