The driver may sleep under a spin lock, and the function call path is:
rtsx_exclusive_enter_ss (acquire the lock by spin_lock)
rtsx_enter_ss
rtsx_power_off_card
xd_cleanup_work
xd_delay_write
xd_finish_write
xd_copy_page
wait_timeout
schedule_timeout --> may sleep
To fix it, "wait_timeout" is replaced with mdelay in xd_copy_page.

Minor clean up, there is no need to assign result to zero, then
check if it is less than zero. Just return SUCCESS.

The retval status checks in the proceeding do loop return out
of function ms_read_attritbute_info if there is an error
condition, thus we never reach the end of the loop with
retval failed status. Therefore, the retval status check
at end of the do loop is redundant and can be removed.
