[PATCH -next] spi: orion: Fix return value check in orion_spi_probe()

[weiyj_lk@xxxxxxx]

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.
