[PATCH 1/1] ov7251: Fix multiple problems in s_stream callback

[Sakari Ailus <sakari.ailus@linux.intel.com>]

The s_stream callback had several issues:

- If pm_runtime_get_sync() fails, the usage_count is not put.

- The mutex wasn't unlocked and the sensor wasn't suspended if
  s_stream(subdev, 1) failed.

Fixes: ("media: i2c: Add pm_runtime support to ov7251")
