HID: amd_sfh: free driver_data after destroying hid device
HID driver callbacks aren't called anymore once hid_destroy_device() has
been called. Hence, hid driver_data should be freed only after the
hid_destroy_device() function returned as driver_data is used in several
callbacks.
I observed a crash with kernel 6.10.0 on my T14s Gen 3, after enabling
KASAN to debug memory allocation, I got this output:

KASAN reports a use-after-free of hid->driver_data in function
amd_sfh_get_report(). The backtrace indicates that the function is called
by amdtp_hid_request() which is one of the callbacks of hid device.
The current make sure that driver_data is freed only once
hid_destroy_device() returned.
Note that I observed the crash both on v6.9.9 and v6.10.0. The
code seems to be as it was from the early days of the driver.
