net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()
The issue happens on some error handling paths. When the function
fails to grab the object `xprt`, it simply returns 0, forgetting to
decrease the reference count of another object `xps`, which is
increased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount
leaks. Also, the function forgets to check whether `xps` is valid
before using it, which may result in NULL-dereferencing issues.
Fix it by adding proper error handling code when either `xprt` or
`xps` is NULL.
Fixes: 5b7eb78486cd ("SUNRPC: take a xprt offline using sysfs")
