xfs: call xlog_state_release_iclog with l_icloglock held
All but one caller of xlog_state_release_iclog hold l_icloglock and need
to drop and reacquire it to call xlog_state_release_iclog. Switch the
xlog_state_release_iclog calling conventions to expect the lock to be
held, and open code the logic (using a shared helper) in the only
remaining caller that does not have the lock (and where not holding it
is a nice performance optimization). Also move the refactored code to
require the least amount of forward declarations.
