scsi: qedf: use correct strncpy() size
gcc-8 warns during link-time optimization that the strncpy() call passes
the size of the source buffer rather than the destination:
drivers/scsi/qedf/qedf_dbg.c: In function 'qedf_uevent_emit':
include/linux/string.h:253: error: 'strncpy' specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
This changes it to strscpy() with the correct length, guaranteeing a
properly nul-terminated string of the right size.
