Sergey Shtylyov 74ea538aa2 nfs: fix undefined behavior in nfs_block_bits() 
commit 3c0a2e0b0a upstream.

Shifting *signed int* typed constant 1 left by 31 bits causes undefined
behavior. Specify the correct *unsigned long* type by using 1UL instead.

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
