[PATCH, 2/2] spi: bcm-qspi: Fix return code from bcm_qspi_flash_read()

[Kamal Dasu <kdasu.kdev@gmail.com>]

To properly fallback to normal mspi reads return appropriate return code to
m25p80_read() function. Changed return code to -EINVAL from -EAGAIN to match
what is expected by the m25p80 driver.
