This reverts commit 8c3ac02bca.
The hook android_vh_mutex_start_check_new_owner 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.
