[PATCH] staging: lustre: lprocfs_status.h: fix sparse error: symbol redeclared with different type

[Samuele Baisi <ciccio87@gmail.com>]

drivers/staging/lustre/lustre/obdclass/lprocfs_status.c:1554:5: error:
symbol 'lprocfs_wr_root_squash' redeclared with different type (originally
declared at drivers/staging/lustre/lustre/obdclass/../include/lprocfs_status.h:704)
- incompatible argument 1 (different address spaces)

drivers/staging/lustre/lustre/obdclass/lprocfs_status.c:1618:5: error:
symbol 'lprocfs_wr_nosquash_nids' redeclared with different type (originally
declared at drivers/staging/lustre/lustre/obdclass/../include/lprocfs_status.h:706)
- incompatible argument 1 (different address spaces)

Added __user annotation to the header definitions arguments (which are
indeed userspace buffers).
