[PATCH] block: blk-merge: Replace == false comparisons with !

[Md Shofiqul Islam <shofiqtest@gmail.com>]

The kernel coding style prefers the negation operator '!' over explicit
comparison against 'false'. Replace four such comparisons in
ll_new_hw_segment(), ll_merge_requests_fn(), and blk_rq_merge_ok().

Also fix a typo in a comment: "occured" -> "occurred".
