usb: Fix error handling in musb_hcd.c
The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success containing the value 0, 1 or -1. This patch changes the return type to an int to accommodate the negative return values. These functions are used in the file using calls such as if (!wait_until... Where a -1 is returned it is mishandled and treated as success instead of a CRC error. This patch addresses this.
