Since commit ba1582f22231 ("usb: gadget: f_hid: use alloc_ep_req()") we cannot allocate any requests in bind() as we check if we should align request buffer based on endpoint descriptor which is assigned in set_alt().Allocating request in bind() function causes a NULL pointer dereference. This commit moves allocation of IN request from bind() to set_alt() to prevent this issue.
