Replace MAX_RECLAIM_RETRIES by vm.max_reclaim_retries

Replace MAX_RECLAIM_RETRIES by vm.max_reclaim_retries

This patch replaces MAX_RECLAIM_RETRIES in mm/internal.h by a new sysctl knob vm.max_reclaim_retries.

This patch may be correctly applied (at least) to Linux 5.4—5.12-rc2.

Default vm.max_reclaim_retries value can be changed via CONFIG_MAX_RECLAIM_RETRIES.

There are two versions with different default values:

• Change_max_reclaim_retries_16_5.10.patch provides vm.max_reclaim_retries with default value 16;
• Change_max_reclaim_retries_0_5.10.patch provides vm.max_reclaim_retries with default value 0.
