Skip mipmap generation for integer sparse texture formats

According to historical records, this is unsupported, and Mesa throws
GL_INVALID_OPERATION to confirm that it is unsupported.

Affects:
KHR-GL46.sparse_texture2_tests.UncommittedRegionsAccess

Components: OpenGL
VK-GL-CTS issue: 3653

Change-Id: I29dc008b6201939b2b7354b0843e018b9db4069c
