ANDROID: ABI: modify exports for find_vma

A previous change [1] inlined find_vma function, resulting in its
removal from the exported kernel symbols and replacement with
__find_vma. This function is implemented in the header file and is
still available to drivers, but exported function is changed to
__find_vma. This causes ABI breakage with the following error:

ERROR: Differences between ksymtab and symbol list detected!
Symbols missing from ksymtab:
 - find_vma

Replace find_vma with new __find_vma in the symbol lists.
