uxa: Cap the maximum number of VMA cached
Since we can not keep an unlimited number of vma cached due to the hard
per-process limits on the number of mappings and recreating mappings is
slow due to excruciatingly slow GTT pagefaults, we need to compromise
and keep a small MRU cache of inactive mmaps.
This uses the new API in libdrm-2.4.29 to specify the limit upon the VMA
cache maintained by libdrm.
