bt: Remove B_BUSY stateskiboot-5.0.5
The bt layer used to cache the value of B_BUSY in the state machine,
assuming that once B_BUSY was cleared by the BMC that it would never
be set by the BMC again unless a message was sent to the bt interface.
This was mostly true for the AMI firmware except when the BMC reboots
which causes B_BUSY to be set. There may also be additional
circumstances which set B_BUSY. Therefore the bt layer must check
B_BUSY is clear before sending a message making the B_BUSY state
superfluous.
