FileManager: Handle possible ByteBuffer allocation failure

Browse source 
Before this patch we created ByteBuffer with the help of the
VERIFY macro that could cause a crash of FileManager
in case of memory allocation failures.

Now we propagate the error to a caller instead of using the
`release_value_but_fixme_should_propagate_errors()` method.
