leds: qpnp-flash: Fix Use-after-free(UAF) for debugfs
Fix UAF where two threads can open and close the same file. Second
open will cause the private data for the first file to be overwritten.
When the first file is closed and the private data is freed, this makes
the now-shared private data OOB for the second thread.
