[PATCH -next] i2c: omap: fix PM reference leak in omap_i2c_probe()

[Li Huafei]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here. Fix
it by replacing it with pm_runtime_resume_and_get to keep usage counter
balanced.
