[PATCH 1/2] target: drop spin_lock_assert() + irqs_disabled() combo checks

[bigeasy@xxxxxxxxxxxxx]

There are a few functions which check for if the lock is held
(spin_lock_assert()) and the interrupts are disabled (irqs_disabled()).
>From looking at the code, each function is static, the caller is near by
and does spin_lock_irq|safe(). As Linus puts it:

|It's not like this is some function that is exported to random users,
|and we should check that the calling convention is right.
|
|This looks like "it may have been useful during coding to document
|things, but it's not useful long-term".

Remove those checks.
