[PATCH] i2c: iproc: Remove redundant error checks for bcm_iproc_i2c_init

[Wentao Liang]

The bcm_iproc_i2c_init() always returns 0. As a result, there
is no need to check its return value or handle errors.

This change removes the redundant error handling code after
calls to bcm_iproc_i2c_init() in both the bcm_iproc_i2c_probe()
and bcm_iproc_i2c_resume().

Fixes: e6e5dd3566e0 ("i2c: iproc: Add Broadcom iProc I2C Driver")
Fixes: 0ee04e91eacd ("i2c: iproc: Add suspend/resume support")
