remove redundant AND from swp_type

Hi,

There is a useless AND in swp_type() function.

We just shifted right SWP_TYPE_SHIFT() bits the value from the swp_entry_t, and then we AND it with "(1 << 5) - 1" (which is a mask corresponding to the number of bits used by "type").

Remove it since its redundant.

This is probably some leftover from old code.
