target-sh4: MMU: fix mem_idx computation

The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0
corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user
mode (SR_MD = 0).

With the current code, the QEMU TLB is setup to match the read/write

is setup in read-only mode. When the page is later accessed in write
mode, an MMU fault happened, and the page is switch in write-only...
