USB: musb_udc: Make musb_peri_rx_ep check for MUSB_RXCSR_RXPKTRDY

The endpoint rx count register value will be zero if it is read before
receive packet ready bit (PERI_RXCSR:RXPKTRDY) is set.

Check for the receive packet ready bit (PERI_RXCSR:RXPKTRDY) before
reading endpoint rx count register. Proceed with rx count read and
FIFO read only if RXPKTRDY bit is set.
