doc: usbmon: fix wording "be reading until"

The usbmon documentation uses "be reading until" which is an uncommon
and confusing wording.  Change it to "read until it" which is more clear.

doc: dynamic-debug: "callsite" should be "call site"

The term "call site" consists of two words, not one.  In code "callsite"
might be an appropriate variable name, but not in documentation.  Fix
all instances in the dynamic debug documentation.

doc: dynamic-debug: remove obvious use of text utils

The dynamic debug documentation describes how the
<debugfs>/dynamic_debug/control file can be displayed using cat.
And then goes on to say that standard text utilities can be used.
It should be obvious to anyone who has used cat before that this
can be done, remove it.

doc: dynamic-debug: remove obvious spaces example

One example describes how commands can be sent to
<debugfs>/dynamic_debug/control with various combinations
 of tabs or spaces.  If the user sends a malformed command
it will be rejected, there is no need to describe this.
Remove these pointless examples.

doc: dynamic-debug: remove obvious "cat file > control"

If a command can be echoed and redirected to the control file
it should be obvious that cat can be used to redirect a whole
file of these commands.  Remove this obvious example.

People reading this document want to know how to use
dynamic-debug, not how to use standard Linux utilities.

doc: dynamic-debug: clean up nullarbor:~ # command examples

Many of the command line examples look they were copied straight
from a terminal and they are preceded with "nullarbor:~ #" which
is distracting.

Clean up the examples by removing the prefix, placing them on one
line where possible, and indenting them with two spaces.
