[PATCH] drbd: Replace if and BUG with BUG_ON

[Amitoj Kaur Chawla]

Replace if condition and BUG() with a BUG_ON having the conditional
expression of the if statement as argument.

The Coccinelle semantic patch used to make this change is as follows:
@ disable unlikely @ expression E,f; @@

(
  if (<+... f(...) ...+>) { BUG(); }
|
- if (unlikely(E)) { BUG(); }
+ BUG_ON(E);
)

@@ expression E,f; @@

(
  if (<+... f(...) ...+>) { BUG(); }
|
- if (E) { BUG(); }
+ BUG_ON(E);
)
