Stafford Horne d82826201f rseq/selftests: Fix riscv rseq_offset_deref_addv inline asm 
commit 713e788c0e upstream.

When working on OpenRISC support for restartable sequences I noticed
and fixed these two issues with the riscv support bits.

 1 The 'inc' argument to RSEQ_ASM_OP_R_DEREF_ADDV was being implicitly
   passed to the macro.  Fix this by adding 'inc' to the list of macro
   arguments.
 2 The inline asm input constraints for 'inc' and 'off' use "er",  The
   riscv gcc port does not have an "e" constraint, this looks to be
   copied from the x86 port.  Fix this by just using an "r" constraint.

I have compile tested this only for riscv.  However, the same fixes I
use in the OpenRISC rseq selftests and everything passes with no issues.

Fixes: 171586a6ab ("selftests/rseq: riscv: Template memory ordering and percpu access mode")
