qla2x00t-32gbit: Backport to older kernel versions

Browse Source 
The commit ec325c9913bd ("qla2x00t-32gbit: edif: Add bsg interface to
read doorbell events") introduced the use of the sg_copy_buffer()
function.

The kernel has only exported this function since version v4.2, so use
sg_pcopy_from_buffer() instead, which is already supported by older
kernel versions.
