[PATCH] ARM: OMAP2+: PM: fix return value check in omap2_set_init_voltage()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

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