[patch] be2iscsi: correct return value in mgmt_invalidate_icds()

[Dan Carpenter <error27@gmail.com>]

This function should return 0 on error.  Returning -1 would cause a
crash.

Also there is an extra space before the newline character and a missing
space between the "for" and the "mgmt_invalidate_icds".  I put the string
on one line.  The current version of checkpatch.pl complains that the
line is too long, but it makes grepping easier.
