net: hns3: Remove un-necessary 'else-if' in the hclge_reset_event()

mainline inclusion
from mainline-v5.12-rc7
commit 0600771f
category: bugfix
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0600771fa6b231e801ba1ff5d7adfcf7659dbbf3



----------------------------------------------------------------------

Code to defer the reset(which caps the frequency of the reset) schedules the
timer and returns. Hence, following 'else-if' looks un-necessary.
