[PATCH] spi: spi-zynq-qspi: Fix some wrong goto jumps & missing error code

[zpershuai]

In zynq_qspi_probe function, when enable the device clock is done,
the return of all the functions should goto the clk_dis_all label.

If num_cs is not right then this should return a negative error
code but currently it returns success.
