USB: storage: ums-realtek: fix error code in rts51x_read_mem()
The rts51x_read_mem() function should return negative error codes.
Currently if the kmalloc() fails it returns USB_STOR_TRANSPORT_ERROR (3)
which is treated as success by the callers.
Fixes: 065e60964e29 ("ums_realtek: do not use stack memory for DMA")
