fs_mgr: report errno string for __mount errors 

Need to know why the mount failed.  clang_format adjustment.

Basically change LINFO to PINFO to cause the log message for the mount
report to be accompanied by a strerror(errno) message appended to the
end so that it is clear why the mount was rejected.

Test: manual
