[8u] RFR: fix of next pc calculation in handle_unsafe_access()

[Fedor Burdun]

Hi all,

Please review fix of crash occurring in regression test (java/nio/MappedByteBuffer/Truncate.java).

The problem is caused by skipping extra instructions in handle_unsafe_access() function after catching SIGBUS signal.
Meanwhile this routine should skip only one instruction (as we can see on other platforms)

The patch is in attachment.

Thanks,
Fedor
