media: rc: clean up leader pulse/space for manchester encoding
The IR rc6 encoder sends the header using manchester encoding using 0
bits, which causes the following:
UBSAN: Undefined behaviour in drivers/media/rc/rc-ir-raw.c:247:6
shift exponent 4294967295 is too large for 64-bit type 'long long unsigned int'
So, allow the leader code to send a pulse and space and remove the unused
pulse_space_start field.
