soc: apple: rtkit: Fix use-after-free in apple_rtkit_crashlog_rx()

This code calls kfree(bfr); and then passes "bfr" to rtk->ops->crashed()
which is a use after free.  The ->crashed function pointer is implemented
by apple_nvme_rtkit_crashed() and it doesn't use the "bfr" pointer so
this doesn't cause a problem.  But it still looks sketchy as can be.

Fix this by moving kfree() after the last usage of bfr.
