Summary
In the Linux kernel, the following vulnerability has been resolved:
ipmi_si: fix a memleak in try_smi_init()
Kmemleak reported the following leak info in try_smi_init():
unreferenced object 0xffff00018ecf9400 (size 1024):
comm "modprobe", pid 2707763, jiffies 4300851415 (age 773.308s)
backtrace:

[<0000000030a59039>] el0_sync+0x160/0x180
The problem was that when an error occurred before handlers registration
and after allocating `new_smi->si_sm`, the variable wouldn't be freed in
the error handling afterwards since `shutdown_smi()` hadn't been
registered yet. Fix it by adding a `kfree()` in the error handling path
in `try_smi_init()`.
