Xin Zhao ea427a222d HID: core: Fix deadloop in hid_apply_multiplier. 
The initial value of hid->collection[].parent_idx if 0. When
Report descriptor doesn't contain "HID Collection", the value
remains as 0.

In the meanwhile, when the Report descriptor fullfill
all following conditions, it will trigger hid_apply_multiplier
function call.
1. Usage page is Generic Desktop Ctrls (0x01)
2. Usage is RESOLUTION_MULTIPLIER (0x48)
3. Contain any FEATURE items

The while loop in hid_apply_multiplier will search the top-most
collection by searching parent_idx == -1. Because all parent_idx
is 0. The loop will run forever.

There is a Report Descriptor triggerring the deadloop
0x05, 0x01,        // Usage Page (Generic Desktop Ctrls)
0x09, 0x48,        // Usage (0x48)
0x95, 0x01,        // Report Count (1)
0x75, 0x08,        // Report Size (8)
0xB1, 0x01,        // Feature
