[tests] do not retry when failed to receive specified number of frames (#11229)

When running the command `diag receive 1 rlp`, the DUT may fail to
receive the frame, then the otci will try the command again and
again. These retries are useless, and they will take lots of time
before timeout.

This commit sets the number of retry to 0 before executing the
command, and restore the number of retry after the command is
executed. This commit also captures the timeout exception from the
adb_shell.
