Colin Ian King 4208c398aa fs/jfs: fix potential integer overflow on shift of a int 
The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then assigned to a signed 64 bit integer. In the case where
l2nb is 32 or more this can lead to an overflow.  Avoid this by shifting
the value 1LL instead.

Addresses-Coverity: ("Uninitentional integer overflow")
Fixes: b40c2e665c ("fs/jfs: TRIM support for JFS Filesystem")
