scsi: lpfc: Correct WQ creation for pagesize
commit 8ea73db486cda442f0671f4bc9c03a76be398a28 upstream. Correct WQ creation for pagesize The driver was calculating the adapter command pagesize indicator from the system pagesize. However, the buffers the driver allocates are only one size (SLI4_PAGE_SIZE), so no calculation was necessary.
