kernel: ipmi_si: fix a memleak in try_smi_init()

A memory leak flaw was found in the Linux kernel's IPMI System Interface driver in the initialization error path. A local user can trigger this issue by loading the ipmisi module when initialization fails after allocating the sism structure but before registering the shutdown handler. This causes...
