[PATCH -next] m68k: fix return value check in mcf_pci_init()

[Wei Yongjun]

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

Fixes: bf114d773167 ("m68k: force use of __raw_read/__raw_write address to be 
iomem")
