Revert "ANDROID: mm/cma: add vendor_hook in cma_alloc to record information"

This reverts commit 0a1ffa01.

The hook android_vh_cma_alloc_fail is not used by any vendor, so remove
it to help with merge issues with future LTS releases.

If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.
