i2c: riic: fix refcount leak in riic_i2c_resume_noirq()

When riic_i2c_resume_noirq() is called, it deasserts the reset
using reset_control_deassert(), which for shared resets increments
a reference count. If pm_runtime_force_resume() then fails, the
function returns without calling reset_control_assert() to
decrement the count. This leaves the reset deasserted and the
reference count unbalanced, which can prevent other users of the
shared reset from properly asserting it later.

Fix the leak by calling reset_control_assert() on the error
handling path for a failed pm_runtime_force_resume().
