Subject: [PATCH] scsi: qla1280: remove redundant variable toke

Variable toke is being assigned a value that is never read. The variable
is redundant, remove it.

Cleans up clang scan build warning:
warning: Although the value stored to 'toke' is used in the enclosing
expression, the value is never actually read from 'toke'
