usb: storage: Drop unnecessary check in usb_stor_blk_io()

Checking that sector_count is zero, shouldn't be necessary since block
layer won't call this function if there's no data to be read. Drop it.

Checking that blockbits is eqal to SECTOR_SHIFT isn't necessary, since
that field is filled by the driver and is not changed outsied of
it. We know it is going to be SECTOR_SHIFT. Drop it.

Checking sector_start > (ulong)-1 doesn't make sense at all since
sector start is 'int' and it can't possibly be greater that
ULONG_MAX. Drop it.

Checking for sector_start >= pblk_dev->blk.num_blocks isn't necessary
either, since we shouldn't receive request for invalid read from block
layer. Drop it.

Ditto for sector_count > INT_MAX and sector_start + sector_count >
pblk_dev->blk.num_blocks.
