tty/serial fixes for 5.0-rc2

Here are 2 tty and serial fixes for 5.0-rc2 that resolve some reported
issues.

The first is a simple serial driver fix for a regression that showed up
in 5.0-rc1.  The second one resolves a number of reported issues with
the recent tty locking fixes that went into 5.0-rc1.  Lots of people
have tested the second one and say it resolves their issues.

Both have been in linux-next with no reported issues.
