scsi: lpfc: Fix field overload in lpfc_iocbq data structure

Browse Source 
The lpfc_iocbq data structure has void * pointers that are overloaded to be
as many as 8 different data types and the driver translates the void * by
casting.  This patch removes the void * pointers by declaring the specific
types needed by the driver.  It also expands the context_un to include more
seldom used pointer types to save structure bytes.  It also groups the u8
types together to pack the 8 bytes needed.  This work allows the lpfc_iocbq
data structure to be more strongly typed and keeps it from being allocated
from the 512 byte slab.

[mkp: rolled in zeroday fix]
