drivers/memstick/core/ms_block.c: fix unreachable state in h_msb_read_page()
In h_msb_read_page() in ms_block.c, flow never reaches case MSB_RP_RECIVE_STATUS_REG. This causes error when MEMSTICK_INT_ERR is encountered and status error bits are going to be examined, but the status will never be copied back. Fix it by transitioning to MSB_RP_RECIVE_STATUS_REG right after MSB_RP_SEND_READ_STATUS_REG.
