Comment (by Sebastian Huber):

 The mmap_mappings_lock attributes don't create a mutex:

 #define RTEMS_MUTEX_ATTRIBS \
   (RTEMS_PRIORITY | RTEMS_SIMPLE_BINARY_SEMAPHORE | \
RTEMS_NO_INHERIT_PRIORITY | RTEMS_NO_PRIORITY_CEILING | RTEMS_LOCAL)

 I suggest to use the libio mutex and keep the specialized lock/unlock
 functions.  Mutex lock/unlock should not return a status code to simplify
 the error handling.

 Fixed issue with searching mapped addresses

 The loop that checks if the current address is already mapped uses
 the same local variable for the chanin node as the newly allocated
 chain node so the allocated chain node gets over written.

 Added a new local variable for the loop that checks the address

 Updates #2859.
