drivers: wifi: simplelink: Fix strings used in assertions

Samples for cc3220sf_launchxl where assertions are enabled
(e.g. http_get) fail to build because some of the strings used in the
simplelink wifi driver have parentheses around them. This breaks the
current implementation of the __ASSERT macro. This commit removes
the parentheses, which are unnecessary.

http_get has been verified to build after this change.

Fixes #12192
