Roman Bacik b925c9de46 i2c: iproc: handle invalid slave state 
[ Upstream commit ba15a14399 ]

Add the code to handle an invalid state when both bits S_RX_EVENT
(indicating a transaction) and S_START_BUSY (indicating the end
of transaction - transition of START_BUSY from 1 to 0) are set in
the interrupt status register during a slave read.
