[PATCH v2] staging/lustre: Different prototypes between the declaration and the definition

["Loïc Pellegrino" <oort10@gmail.com>]

Align the prototype of lprocfs_wr_uint() in the declaration with the one used 
in the definition.

The prototype is:
int lprocfs_wr_uint(struct file *file, const char __user *buffer,
                    unsigned long count, void *data)
In obdclass/lprocfs_status.c

But in lustre/include/lprocfs_status.h, the __user annotation is missing for 
the attribute buffer.

The correct prototype is the first one (the definition) since:
- This function is eventually called by the write() function pointer of an 
instance of struct file_operations
- In this function, buffer is a parameter of copy_from_user()
- Before the commit 73bb1da692d0dc3e93b9c9e29084d6a5dcbc37a6, the declaration 
and the definition had the same prototype, but only the .c has been updated.

Correcting this will remove a sparse error and add sparse warnings.
This is a task of the Eudyptula challenge.
