staging/android: drop sync_file_install() and sync_file_put()

From: Gustavo Padovan <[email protected]>

These two functions are just wrappers for one line functions, they call fd_install() and fput() respectively, so just get rid of them and use fd_install() and fput() directly for more simplicity.

Given sync_file is not file, I don't see that simplicity is worth of the change of 20+ lines.
Can you please specify the disadvantages of the wrappers?
