Colin Ian King f52688ce0d rsi: fix memory leak on buf and usb_reg_buf ...

[ Upstream commit d35ef8f846 ]

In the cases where len is too long, the error return path fails to
kfree allocated buffers buf and usb_reg_buf.  The simplest fix is to
perform the sanity check on len before the allocations to avoid having
to do the kfree'ing in the first place.
