Ahmad Fatoum 0004122763 mtd: spi-nor: fsl-quadspi: Don't let -EINVAL on the bus 
fsl_qspi_get_seqid() may return -EINVAL, but fsl_qspi_init_ahb_read()
doesn't check for error codes with the result that -EINVAL could find
itself signalled over the bus.

In conjunction with the LS1046A SoC's A-009283 errata
("Illegal accesses to SPI flash memory can result in a system hang")
this illegal access to SPI flash memory results in a system hang
if userspace attempts reading later on.

Avoid this by always checking fsl_qspi_get_seqid()'s return value
and bail out otherwise.

Fixes: e46ecda764 ("mtd: spi-nor: Add Freescale QuadSPI driver")
