[PATCH v2 v2] IB/iser: fix typos in iscsi_iser.c comments

[Imanol <imvalient@protonmail.com>]

Fixes multiple occurrences of the misspelled word "occured" in the comments
of `iscsi_iser.c`, replacing them with the correct spelling "occurred".

This improves readability without affecting functionality.
