nfs: fix undefined behavior in nfs_block_bits()
commit 3c0a2e0b0ae661457c8505fecc7be5501aa7a715 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.
