Subject: [PATCH v2] ath11k: simplify if-if to if-else

Replace `if (!ab->is_reset)` with `else` for simplification
according to the kernel coding style:

"Do not unnecessarily use braces where a single statement will do."

...

"This does not apply if only one branch of a conditional statement is
a single statement; in the latter case use braces in both branches"

Please refer to:

why are you referring to braces when your patch has nothing to do with
braces?

changing if (foo) X;if (!foo) Y; to if (foo) X else Y; is not a design
pattern referenced in the coding style
