[PATCH 2/2] staging: android: ion: One function call less in ion_buffer_create() after error detection

The jump label "err1" was used by the ion_buffer_create() function in case of
a memory allocation failure just to pass a null pointer to a vfree() function
call by a data structure element.
This implementation detail could be improved by the deletion of this
inappropriate jump label.
