[PATCH 1/1] mm: Correct misleading comment on mmap_lock field in mm_struct

[Adrian Huang <adrianhuang0701@gmail.com>]

From: Adrian Huang <ahuang12@lenovo.com>

The comment previously described the offset of mmap_lock as 0x120 (hex),
which is misleading. The correct value is 120 (decimal), and using '0x120'
could confuse readers trying to understand why the count and owner fields
reside in separate cachelines.

This change also removes an unnecessary space for improved formatting.

Fixes: 2e3025434a6b ("mm: relocate 'write_protect_seq' in struct mm_struct")
