qedi_dbg_err(), qedi_dbg_warn(), qedi_dbg_notice(), and qedi_dbg_info()
format their variadic arguments via struct va_format and %pV, but unlike
their counterparts in qedf_dbg.h, they lack __printf() attributes in
qedi_dbg.h.

Add the missing __printf(4, 5) and __printf(5, 6) annotations to
qedi_dbg.h and fix the resulting -Wformat warnings exposed across
qedi_fw.c and qedi_main.c:

 - Use 0x%x instead of 0x%p for cqe->rqe_opaque (u16).
 - Use 0x%x instead of 0x%llx for pbl->address.hi and lo (__le32).
 - Use 0x%lx instead of 0x%x for qedi->qedi_err_flags (unsigned long).
