From the data sheet TXCOMP is only set after a stop or repeated start and address change, but EOSACC is set for a stop or repeated start when the address remains the same. This change removes the check for TXCOMP when not idle, to support repeated starts for both RX and TX.

From the SAM3X Datasheet
Section 33.11.6:
With a repeated start and same address it will not be set, however EOSACC will be as shown in Figure 33-30 and 33-31.
This change removes the check for TXCOMP, and only checks for EOSACC to be set when not idle, to return back to the idle state. This enables support repeated starts for both RX and TX in slave mode.
