Test "Protocol desync regression test" in test_protocol.tcl do nothing.

[netanelrevah]

this is the test:

if {$::tls} {
                set s [::tls::socket [srv 0 host] [srv 0 port]]
            } else {
                set s [socket [srv 0 host] [srv 0 port]]
            }
            puts -nonewline $s $seq
            set payload [string repeat A 1024]"\n"
            set test_start [clock seconds]
            set test_time_limit 30
            while 1 {
                if {[catch {
                    puts -nonewline $s payload
                    flush $s
                    incr payload_size [string length $payload]
                }]} {
                    set retval [gets $s]
                    close $s
                    break
                } else {
                    set elapsed [expr {[clock seconds]-$test_start}]
                    if {$elapsed > $test_time_limit} {
                        close $s
                        error "assertion:Valkey did not closed connection after protocol desync"
                    }
                }
            }
            set retval

the test write null "\x00" to the server and then write a lot of "payload" string.

then get the error "-ERR Protocol error: too big inline request\r\n"

it will also fail the same without sending any of the \x00 character.

we should choose from:

1. fix the test
2. fix the \x00 behaviour as excpected
3. remove the test
