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.
Fixes: ba1582f22231 ("usb: gadget: f_hid: use alloc_ep_req()")
