USB: composite: Re-allocate bytes for IN endpoint

Browse Source 
Switching to kzalloc doesn't mean we can't allocate some extra bytes
for the TX buffer. This was simply an improper merge of commit [1]
by CodeLinaro. The commit was just supposed to replace kmalloc with
kzalloc. Therefore, add back the buffer allocation.

[1]: ae9cf8b759 ("UPSTREAM: USB: gadget: zero allocate endpoint 0 buffers")

Fixes: ae9cf8b759 ("UPSTREAM: USB: gadget: zero allocate endpoint 0 buffers")
