        sys/dev/i2c/sdtemp.c: revision 1.37

KNF. No functional change.

  Check the return value of iic_acquire_bus(). This function may fail.

  One of the case is driver's detaching phase on shutdown. mutex_tryenter()
might fail and return with EBUSY. To avoid calling iic_release_bus() without
taking lock, check the return value of iic_acquire_bus().

  If an error occurred in sme_refresh function, pass ENVSYS_SINVALID.
