Correct an 'unresolved identifier' problem caused by an "inline"

function being used before it was defined - "forward" declaration
was insufficient.


innobase/lock/lock0lock.c:
  Compile problem on 'build', solved by moving the definition of
  'lock_rec_get_nth_bit' to the place of the ("forward") declaration.
  It is "inline", and now the body really appears before the first use.
