Completes the filp_open/kernel_read/kernel_write removal pass
across the driver. Deletes bes_fw.c DATA_DUMP_OBSERVE blocks
(4 #ifdefs gated on a commented-out #define, dead by default;
would fail to build on modern kernels due to removed
get_fs/set_fs) and main.c's orphan access_file() helper
(no callers in-tree, also relies on get_fs/set_fs).
With c1.2 + c1.3 + c1.4 combined: zero filp_open /
kernel_read / kernel_write / vfs_read / vfs_write references
anywhere in the driver -- precondition for a linux-wireless
RFC for drivers/staging/bes2600/ unlocked.
Deployed + verified on ohm (srcversion 12BAFB9C…): WiFi
associated, no KFENCE / sdio_tx_work / RX failure / PS Mode
Error / factory cali data get failed. Net: -69 lines.
